Southeast Asian Port Cities

Abstract
The historical ports of Southeast Asia were highly active regional
mercantile hubs located at the crossroads between the East Asian and
Indian Ocean trading networks. These strategically places attracted
merchants and sailors from the world over, some of whom stayed on a
permanent or semi-permanent basis to carry out their business. By their
very nature, Southeast Asian ports are thus both economic spaces
dedicated to maritime activities, and cosmopolitan spaces where people
from different social and cultural backgrounds came together. This duality
is expressed in the built environment, which contains specialised
structures to facilitate trade (such as wharves, warehouses, and
boatyards) but also communicates people’s identity. This paper proposes
studying historical port cities by combining a maritime cultural landscape
approach and urban social theory to understand the economic as well as
the socio-cultural fabric of Southeast Asian ports.
This approach will be applied to two very different port cities: Hội An in
Central Vietnam, and George Town in Malaysia. Whereas Hội An was an
informal temporary market place that grew to be one of the region’s
biggest entrepôt ports in the 18th century, George Town was founded as
a trading outpost for the British East India Company in 1786, before
becoming the seat of many mercantile firms and banks in the 19th century.
Key words: ports, economies, structures, socio-cultural

Introduction
Ports, by their nature, are highly economic spaces dedicated to maritime
activities. The ports of Southeast Asia, strategically located at the
crossroads between the East Asian and Indian Ocean trading networks

�(and by extension the East-West trading network), were chiefly stopovers
and entrepôts through which moved traders from all corners of the world.
Due to the monsoon trade, merchants would often stay in these ports for
months at a time waiting for the winds change, and created settlements
where the various traditions would intermingle, yet remained distinct (Li,
1998; Lockard, 2010; Reid, 1993). Southeast Asian port cities were thus
— in addition to being highly economic — also highly culturally and
socially diverse; in other words they were cosmopolitan. Craig Lockard
(2010) described them as “places of economic exchanges as well as
cosmopolitan gateways for the import and export of people, goods, and
ideas.” This paper proposes to apply a maritime cultural landscape
approach in conjunction with the environment-behaviour theory in order to
highlight this duality and understand the fabric of historic Southeast Asian
ports.
This paper will address two case studies to illustrate this dual approach:
Hội An in Vietnam, and George Town in Malaysia. Both are inscribed on
the UNESCO World Heritage List, Hội An in 1999 and George Town in
2008, under criterion (ii): “to exhibit an important interchange of human
values, over a span of time or within a cultural area of the world, on
developments in architecture or technology, monumental arts, townplanning or landscape design” (UNESCO, 2016).1 Hội An is located on the
Thu Bon river in Quảng Nam province in central Vietnam. It was
established as a foreign port for the Nguyen Lords some time in the mid
to late sixteenth century, though the exact date and circumstances are
unknown (Dror and Taylor, 2006; Wheeler, 2006). Hội An was a
successful entrepôt until the eighteenth century when was eclipsed by Đà
Nẵng, a few kilometres north. During this time, the Japanese and the
Chinese were the two largest foreign trading groups in Hội An. George

�Town, Penang was established in 1786 by Sir Francis Light as an East
India Company free port and naval base (though the naval base did not
actually succeed) (Hussin, 2009). It was the first British port city in
Southeast Asia, and had attracted over ten thousand Malay, Chinese, and
Indian merchants within a decade (Hussin, 200; Lewis, 2016).
Theoretical Background
Both the maritime cultural landscape and environment-behaviour
concepts ultimately aim to understand tangible manifestations of culture,
the former from an archaeological perspective and the latter from an urban
studies perspective. Underlying these concepts are discussions regarding
the nature of culture. The urban theorist Amos Rapoport (1998)
summarizes

the

scholarship

on

culture

by

presenting

three

complementary views of culture: “one view defines it as a way of life typical
of a group; the second, as a system of meanings and schemata
transmitted through symbolic codes; the third, as a set of adaptive
strategies for survival related to ecology and resources.” He views culture
as too abstract for his purposes (understanding culture in the built
environment); it is unobservable and thus “essentially useless” in
environment-behaviour studies (Rapoport, 1998). It is instead the “effects,
expressions, or products” of culture, such as social variables, that are
visible and useful (Rapoport, 1998). He describes increasingly specific
expressions of culture in order to arrive at something actionable: lifestyles
and activity systems. A lifestyle is “the outcome of choices about how to
allocate resources,” in other words; it is composed of a series of activities,
and is influenced by norms, standards and expectations (Rapoport, 1998).
Christer Westerdahl arrived at a similar conclusion regarding maritime
culture specifically, as will be described below.

�Maritime archaeologists have long debated whether there is such a thing
as a distinct maritime culture — that is a culture specific to communities
living on or near the sea that is inherently and completely different to
inland culture. Many have concluded that the separation between land
and sea is not in fact absolute (Tuddenham, 2010; Westerdahl, 2007,
2011). Indeed, humans do not ever exclusively experience the sea
unconnected to land (Mushynsky, 2011; Tuddenham, 2010; Westerdahl,
2007, 2011). Christer Westerdahl (2007) explains that maritime culture is
“eminently a mixture, a creolization, of others. It is based on the
subsistence gained from the seas and the water, and consists of all the
thought patterns, cosmologies, customs, objects, phenomena and
patterns of action connected with a life by the sea.” Like Rapoport, his
view of culture is ultimately related to subsistence strategies, even
referring to the “life mode” concept, and conceptualizing the maritime life
mode as a series of subsidiary trades dictated in this case by living on the
coast or related to a primary maritime trade, not unlike Rapoport’s lifestyle
concept (Westerdahl, 1992, 2007). Some examples he presents are
fishing, hunting, and gathering (at sea or on land), as well as boat building,
shipping, ferrying, pilotage, and lighthouse attendance (Westerdahl,
2007). It is this recurring idea of culture as a “mixture” of activities that
guides this paper. In order to understand the cultural fabric of Southeast
Asian ports, a port should be seen as a sum of parts: a trading community,
a crossroad of sea routes, and a concentration of different traditions.
Ports are often described in the literature as transit points: the point of
change between land and sea, of changing modes of transportation, and
of exchanging goods and ideas (Lockard, 2010; Reid, 1993; Parker, 2001;
Westerdahl, 1992, 1999, 2006, 2011). They are also, in Westerdahl’s
(2006, 2011) words, “maritime enclaves:” semi-permanent or permanent

�settlements engaged in maritime activities. As he conceptualises maritime
culture as a concentration of maritime activities, these enclaves can be
considered the origin of maritime culture, as well as its centre
(Westerdahl, 2006, 2007). In them are thus found the “remains,” or
expressions, of maritime culture such as sailing marks, beacons, loading
places, anchorages, inns, and other cultural deposits (Westerdahl, 2006).
Likewise, Jan Bill and Birthe Clausen (1999) argue that maritime trade
directly impacts the physical development and appearance of towns,
giving them a distinct “maritime town topography.” These are towns that
developed around a port or harbour, and thus had to build specialised
structures such as wharves, jetties, warehouses, and boatyards in order
to participate in maritime trade.
This perspective on ports focuses on its economic fabric, not without
reason considering their role. It is predicated on Westerdahl’s (1992)
innovative maritime cultural landscape concept, which represents “human
utilisation (economy) of maritime space by boat: settlement, fishing,
hunting, shipping and its attendant sub-cultures.” The maritime cultural
landscape is thus a visualisation of people’s relationship to the sea, in
particular with regard to economic exploitation. Many of Westerdahl’s
definitions of the concept focus on seafaring, for example a later one in a
paper about roads and sea routes describes it as the “network of sea
routes, with harbours and related constructions and remains of human
origin, below as well as above the water” (Westerdahl, 2006). Maritime
enclaves are thus the nodes of this network, where maritime culture
comes about and a concentration of “constructions and remains” are
found. Much of Westerdahl’s discussions still focus on economy and
transport, because “their occupations […] to a large extent define their
culture” and “living in an ecological niche leads to an adaptation precisely

�to that niche” (Westerdahl, 2007). Indeed maritime, riverine, and
lacustrine environments tend to develop a culture of transport and
communication characterised by rapid transmission of information and
spatially extended networks (Westerdahl, 1999, 2006). Thus, taking a
maritime cultural landscape approach— as Westerdahl defines it —helps
highlight the adaptations specific to maritime environments and maritime
activities.
This approach however risks overemphasizing the economic role of trade
in the development of ports, to the detriment of social and cultural factors.
As has been reiterated throughout this paper, ports are very diverse
spaces by virtue of their need and ability to attract merchants from all over
the world. Along with goods to trade, these merchants bring with them
their culture: their beliefs, their values, their lifestyles, their tastes in food,
clothes, and architecture... The interaction of people from different social
and geographical backgrounds, all of whom are trying to maintain their
identity, is reflected in the built environment.
Adam Rogers (2013) argues for a more social approach to port and
harbour archaeology, as he believes that studies of ports have focused
too often on how changing technologies (including the characteristics of
ships) and commercial trends have impacted the design of harbours.
Paralleling Rapoport and Westerdahl, Rogers brings up the concept of
“taskscapes,” explaining that the environmental context of ports, the
waterfront, dictates the type of activities people engage in, which in turn
influences the shape of the port (Rogers, 2013). He however goes beyond
this idea by reminding scholars that “by their nature and function, the
connection [of ports] with places across water and overseas means that
they could often attract a large range of different peoples with varying
perspectives” (Rogers, 2013). He proposes drawing from the domestic

�architecture discourse as one way of highlighting the diversity of people
living in ports but points out that in a port setting, it might be difficult to
separate “domestic” and “business” (Rogers, 2013).

Environment-

behaviour theory does not necessitate such a distinction, which is why it
is well suited to the study of ports.
As stated above, Rapoport’s environment-behaviour theory posits that
certain aspects of culture, lifestyles and activity systems, are observable
in the built environment. He states that in order to understand culture fully
in built structures, it is the “latent aspect of activities,” meaning, which
must be considered (Rapoport, 1998). This meaning is connected to
values and social variables such kinship, gender, social roles, and status,
and is transmitted through symbolic codes; it is thus reflected in the choice
of things like colour, material, and spatial organisation (Rapoport, 1998).
Rapoport (1998) illustrates his point with the example of the kitchen: food
preparation varies greatly across cultures, it is also related to other
activities and meanings (for example rituals, familial ties, gender roles), all
of which affect the design of the kitchen and location within the house. In
short, buildings reflect the wants and needs of its users in their structure,
layout, and decorative elements. As lifestyles are expressed in the built
environment, maritime culture is expressed as “a recurrent set of maritime
traits and repetitive maritime behaviour,” which is visible in the
archaeological record (including the built environment) (Mushynsky,
2011). David Tuddenham (2010) puts forward the concept of “maritimity”
to help guide studies of maritime culture. This concept is based on the
idea that material culture is rarely either maritime or terrestrial, rather
somewhere on a scale between the two. In order words, determining
maritimity asks “how maritime is this?” It is however “to be understood as
a category of understanding, not something with empirical qualities,” the

�same way that thinking of life modes, activities, and social variables helps
understand (maritime) culture (Rapoport, 1998; Tuddenham, 2010;
Westerdahl, 2007).
The maritime cultural landscape approach in conjunction with the
environment-behaviour theory provides a conceptual structure with which
to understand the fabric of Southeast Asian port cities, and in particular
how maritime trade influenced their development. It is clear that the
economic and technological aspects of trade highly dictate the use of
space. Their reason for being and their continuing success hinges on the
efficiency with which merchants can participate in regional and/or global
trade. On the other hand, it is important to continuously remember that
around the ports grew towns built by foreign people. In order to
understand a Southeast Asian port, one must consider how the Chinese,
or European, or Indian trader experienced the setting and how (or if) they
maintained their identity.
The Development of Hội An
The practical application of the above approach can take many forms by
focusing on different aspects and characteristics of the port in question.
For example, one could look at community-specific trade practices, the
way they were adapted to function in a foreign port, and the way they may
have been expressed in specialized structures. Another avenue of enquiry
would be to compare the inns and hostels of different communities within
a same port. Westerdahl sees inns as a major feature of the maritime
cultural landscape, acting as relay stations and safe havens in an
emergency (Westerdahl, 2006, 2007). The Chinese, Japanese, British,
and Indian people of Hội An and George Town had similar institutions that
served as accommodation and aid for visiting members of their
communities. Though a cross-cultural study would more fully address the

�question of cosmopolitanism, this paper will focus on a single foreign
merchant community. It will analyse the public buildings and residences
of the Chinese merchant communities in Hội An and George Town in
order to understand the impact of trade on its lifestyle.
The overseas Chinese community represents a large group of migrants in
Southeast Asia, who have played important roles in the history of the
region since the third century before the Christian Era (Mackie, 1996;
Wu, 2010). It is composed chiefly of groups from the southern provinces
of China, especially Fujian and Guangdong. Due to the mountainous
geomorphology of their home, the inhabitants of this region did not
establish very strong ties with Central China, instead turning to the sea
and developing mercantile and fishing activities, and later being highly
involved in regional and global trade. In addition, population pressures
such as poverty, war, and disease, resulted in migration towards
Southeast Asia, in particular after the Qing conquest of the Ming in 1644
and in the second half of the nineteenth century as a result of the two
Opium Wars (1840–1842, 1858–1860) and the Taiping Rebellion (1851–
1864) (Wu, 2010).
The Chinese communities living in Hội An and George Town immigrated
at different times and for different reasons. The first Chinese to arrive in
Hội An after its establishment were highly involved in maritime commerce,
either as traders themselves or running businesses to support trade
(Chen, 2002). This was a relatively small group, outnumbered by the
Japanese until the mid-seventeenth century. The Togukawa policies of
the 1630s prevented Japanese nationals from leaving Japan, leaving a
vacuum in Hội An which was quickly filled by the Chinese (Wheeler,
2001). Furthermore, a substantial number of Ming loyalists sought refuge
in Hội An in 1644; they were given a special status, Minh Hương, which

�allowed them the right to own land, marry local women, and hold office
(Chen, 2002). The height of Hội An’s success, the eighteenth century,
coincided with what Anthony Reid (1993) and Carl Trocki (1997) refer to
as the “Chinese century” when the Qing rescinded the Ming trading bans
and breathed new life into the junk trade. Contemporary visitors to Hội An
often describe the town as a Chinese town, and comment on the affluence
of their neighbourhood (Chen, 2002; Morel, 2010; Wheeler, 2001). The
exact number of Chinese living in the Nguyen port is unclear: Thomas
Bowyear counts around 100 Chinese households in 1696; an anonymous
source counts 6,000 Chinese in 1744, while another estimates 10,000
“married and tax-paying Chinese” in 1750 (Chen, 2002; Dalrymple, 1791–
1797).
The bulk of Chinese immigration in Penang takes place over a century
later, during the decline of the junk trade and the integration of Chinese
merchants into the global capitalist system (Wu, 2010). The majority of
Penang’s early Chinese migrants in fact were not from China but from the
Malay Peninsula, mostly from Kedah (Hussin, 2009). Only the wealthiest
Chinese participated in trade, as owners of shops, shop houses, and ships
or members of mercantile companies; while the majority worked for wages
as skilled, semi-skilled, and unskilled labour (Hussin, 2009). Along with
the Indian community (Chulias), the Chinese community formed the bulk
of George Town’s population; the number of Chinese grew steadily in the
first decades of the nineteenth century, overtaking the number of Indians
in 1828 (Hussin, 2009). Both communities dominated the commercial
centre bounded by Light Street, Beach Street, Chulia Street, and Pitt
Street (Hussin, 2009).
Despite these inceptive differences, there are many similarities in the
Chinese settlements in Hội An and George Town, particularly with regard

�to economic and cultural institutions. The first thing to note is that the
“Chinese community” in both these ports was in fact several communities,
dictated by clan or hometown, each with distinct traditions and languages
(Hussin, 2009). Often, they would create associations, guilds, or societies
according to dialect or family name, which provided a sense of comfort
and belonging to its members. This institution has purely economic origins
in fifteenth century trade guilds that helped regulate business abroad
(Moll-Murata, 2008; Naquin and Rawski, 1987; Purcell, 1965; Wu, 2010).
The associations in Southeast Asia, named kongsi, provided lodging and
a meeting space for visiting merchants, and offered assistance to new
settlers, but also served as a storage facility and as the custom house
(Naquin and Rawski, 1987). Oftentimes, they would take on the role of a
municipal government for the local overseas Chinese population,
providing fire-fighting, policing, and schooling services, as well as
maintaining public infrastructure (Moll-Murata, 2008; Naquin and Rawski,
1987; Wu, 2010). At the end of the 19th century, the kongsis lost their
economic and regulatory roles, instead becoming hui guan: commonorigin associations and public assembly places that promote history and
traditional knowledge (Moll-Murata, 2008; Wu, 2010). The institution is
made concrete in the form of assembly halls and clan houses that are
considered symbols of their community, reflecting unity, loyalty, and
prosperity.
In Hội An there are five Assembly Halls: four common-origin guilds
(Fujian, Guangdong, Teochew, and Hainan) and the Trung Hoa guild that
brings together all the Chinese communities; the latter was originally
established as the Dương Thương guild, the guild for Maritime Commerce
(Chen, 2002). It is notable that an association intended as a professional
guild for the main economic activity of Hội An later came to be a pan-

�Chinese cultural space. In addition to accommodating travelling
merchants and drafting an ethical code of conduct in trade, Dương
Thương hall contained a shrine to the Goddess of Mercy2, the patron of
fishermen and sailors, and the first deity for whom overseas Chinese
would erect a shrine after sailing away from home to settle in a new place
(Chen, 2002; Purcell, 1965). Today’s Trung Hoa Assembly Hall still
maintains the shrine, which now also contains a model of a Chinese junk.
There are some 170 Chinese associations in George Town relating to clan
or dialect; some are headquartered in shop houses, such as the Ch’ng Si
Soo Bee Tong (now Persatuan Zhuang &amp; Yan Pulau Pinang), though most
are housed in grand hall such as Lim Kongsi. The Lim clan had been
trading in Penang since 1821 and established their clan house in 1863 on
Beach Street, the busiest commercial street of George Town, located on
the waterfront until the reclamation projects in the 1870s and 1880s
(George Town World Heritage Incorporated, n.d.; Langdon, 2015). Like
the Dương Thương in Hội An, Lim Kongsi pays tribute to the goddess of
seafarers. She is a recurrent figure around George Town, including at
Kuan Im Teng temple, the oldest Chinese temple in Penang built in the
eighteenth

century.

The associations and halls are a public expression of the Chinese
merchant identity. In the above examples, the sea plays a clear role in the
way the community both views itself and connects with each other. As a
community of seafarers, the sea represents to the Chinese merchant
group a connection and a divide from home, yet it is also their livelihood.
The central role of maritime trade is further illustrated in Hội An and
George Town’s predominant style of housing: the shophouse. As its name
suggests, the shophouse is both a commercial and residential space. The
shop is located at the front of the building, opening on the street, and is

�generally larger than the residential part, which is located in the back or
on the top floor. In Hội An, the shop houses are built as near as possible
to the water to facilitate loading and unloading from ships. Though the
basic layout remains the same, the materials and ornamentations varied
slightly from Hội An to George Town. The Hội An shop houses were
mostly built from an incredibly strong local wood called tin (ironwood); the
early George Town houses had attap roofs, while the later houses were
built of burnt clay bricks (Dror and Taylor, 2006; Hussin, 2009). The
houses in Hội An were also built with flooding in mind, as the river was
known to overflow during the monsoon; they had removable boards and
pulley systems to protect goods (Dror and Taylor, 2006; Morel, 2010). The
façade of shop houses in George Town very distinctly reflected the
ethnicity of its owner through ornamentation: “carved wood panels and
fascia boards of the indigenous and Indo-Malay, elaborate and
superstitious images of the Chinese, the arches of Mogul India, the neoclassical elements of British architecture of the Georgian and Regency
periods and the modernism of art deco and modern architecture” (World
Heritage Site Special Area Plan SAP §A4.11.8).
Conclusion
This analysis of Chinese public and private buildings in Hội An and
George Town has helped understand one aspect of the fabric of
Southeast Asian ports. The overseas Chinese merchant community was
a significant presence throughout the region and thus highly impacted
both its economy and society. However, this study has also shown that
their seaward migration and activities in trading has impacted their lifestyle
and culture. The built environment reflects the dual relationship of this
group with the sea: there is a preoccupation with efficiently utilizing it for

�trading and an understanding of it as something that both separates and
connects them to the homeland.
The theoretical approach outlined in the first section of this paper
considers the port both as part of the maritime cultural landscape and as
a maritime cultural landscape in and of itself in order to visualise how the
economic and technological aspects of maritime trade impact its form and
development. It also proposes focusing on the built environment in order
to draw out the characteristics of a cosmopolitan port culture, based on
the idea that trade forces cosmopolitanism, that is the coexistence of
various cultural groups in one space. The reverse relationship has not yet
been investigated. With the same approach, it may be possible to
visualise how cosmopolitanism impacts trade (the same way it impacted
architecture as seen in the evolution of shop houses in George Town),
where

the

specialised

trade

structures

(wharves,

warehouses,

customs…) would reflect adaptations to new environments and new
people.

                  <text>Southeast Asia (SEA) has been rich in maritime and underwater cultural heritage (UCH) over a long period, from ancient pre-history, through the age of commerce, into the World War II era. Recently, UCH research, survey, and mapping activities; preservation and management efforts; as well as human capacity building programs show the promising progress in SEA countries. However, various threats to UCH preservation and some shortcomings still can be found in many SEA countries, for instance, lack of funds, inadequate technology, limited human resources, and also lack of public and government attention to UCH legal protection and its long-term preservation.    &#13;
&#13;
This session will highlight some topics, including current status of UCH preservation; current research or investigation on maritime heritage or UCH in SEA countries; maritime history in SEA; current legislations; recent human and natural threats to UCH in SEA countries; raising awareness and public education programs; in-situ preservation of UCH; sustainable shipwreck tourism development and balancing preservation efforts with economic benefit; community and general public engagement in UCH management plan; regional capacity building in Southeast Asia; as well as collaboration opportunities among stakeholders and SEA countries in researching, protecting, preserving, and managing UCH sites.&#13;

                <text>The historical ports of Southeast Asia were highly active regional mercantile hubs located at the crossroads between the East Asian and Indian Ocean trading networks. These strategically places attracted merchants and sailors from the world over, some of whom stayed on a permanent or semi-permanent basis to carry out their business. By their very nature, Southeast Asian ports are thus both economic spaces dedicated to maritime activities, and cosmopolitan spaces where people from different social and cultural backgrounds came together. This duality is expressed in the built environment, which contains specialised structures to facilitate trade (such as wharves, warehouses, and boatyards) but also communicates people’s identity. This paper proposes studying historical port cities by combining a maritime cultural landscape approach and urban social theory to understand the economic as well as the socio-cultural fabric of Southeast Asian ports.&#13;
&#13;
This approach will be applied to two very different port cities: Hội An in Central Vietnam, and George Town in Malaysia. Whereas Hội An was an informal temporary market place that grew to be one of the region’s biggest entrepôt ports in the 18th century, George Town was founded as a trading outpost for the British East India Company in 1786, before becoming the seat of many mercantile firms and banks in the 19th century.</text>

Abstract
The Mongols created the world‟s most powerful empire in the thirteenth century, conquering
China and establishing the Yuan dynasty. Their military power was in doubt, however, after failed
naval invasions in Japan and Vietnam. According to historical records, the Vietnamese tactics
used against the Mongolian Armada were designed to prevent them from reaching the mouth of
Bach Dang River by using hidden stakes that were driven into the riverbed in secrecy. Using the
large difference in tides, the Vietnamese successfully lured the enemy fleet into the trap,
destroying or capturing perhaps as many as 400 vessels. Since the 1950s, approximately 700
years after this watershed event, Vietnamese archaeologists have discovered a number of large
wooden stakes in the midst of reclaimed paddy fields along the Bach Dang River. Excavations
and research were conducted which led to the identification of several stake-yard sites believed
to be dated to the battle that took place in 1281 C.E., however, no remains of ships have been
identified to date.
In 2009, a group of scholars from the Institute of Archaeology at Hanoi, the Institute of
Nautical Archaeology at Texas A&amp;M University, and the Maritime Archaeology Program at
Flinders University joined the archaeological investigations of these stake-yard sites with a focus
on studying the battle strategy used by the Vietnamese and identifying ship remains from the
battle. This joint paper will present an intermediate result of this international cooperative project
in maritime archaeology in Vietnam at the naval battle site related to the thirteenth century
Mongolian invasion of the country. The team has identified several new areas of concentrated
stakes and the distribution pattern may lead to better understanding of the battle and the possible
location of shipwreck sites.

Introduction
Since 2008 the international research team the Bach Dang Battlefield Research
Group, comprises of scholars from the Institute of Archaeology in Hanoi
(Vietnam), the Institute of Nautical Archaeology at Texas A&amp;M University (United
States of America), the Maritime Archaeology Program at Flinders University
(Australia) and others. Over the last three years, it has conducted archaeological
survey and excavations at Bach Dang in Vietnam. This investigation of the
maritime cultural landscape encompasses the topography, archaeological
evidence and later memorials, temples and shrines associated with a historically
significant naval battle that took place there in 1288 AD2. A key part of this
research is to develop a better understanding of the battlefield with a focus on

�studying the strategy used by the Vietnamese Dai Viet people. This research
involves the archaeological investigation of wooden stakes that survive from the
battle and remote sensing surveys, as well as conducting interviews with local
fishermen and farmers, in order to locate areas with possible ship remains and
related finds. The work has been designed as a comprehensive project that is
expected to grow to encompass more research issues and include other
researchers.

Context
In 1271 AD Kublai Khan, the fifth emperor of the Mongol Empire (1260-1294),
became the founder of the Yuan Dynasty in China (Gascoigne 2007:137-150;
Ebrey 1996:172-3). On several occasions, from 1274 AD onwards, Kublai Khan
dispatched armies aboard fleets of ships in attempts to expand the empire‟s
hegemony and extend his rule into East Asia (Japan) and Southeast Asia
(Vietnam). Two highly significant locations associated with these attempted
Mongol invasions have been identified – along coast of Takashima Island and in
Bach Dang River. These are places where historically important naval battles are
known to have taken place, in each case resulting in the defeat of the Mongolian
fleets by the local people (Delgado 2009; Ngo 1993:Vol.II, 61). In addition,
archaeological and material culture remains associated with the fleets and battles
have been found at both locations (Sasaki 2008; Tong, et al. 1988; Le and Ha
2005; Le, et al. 2009a; Le, et al. 2011; Sasaki 2009). One area is located off the
shores of Takashima Island in the northwestern Kyushu Islands of Japan where
Mongol invasion fleets are believed to have been sunk by a large typhoon during
the invasion in 1281 AD (Delgado 2009; Kimura 2006; Sasaki 2008; Sasaki this
volume). The other area is located on the Bach Dang River in northern Vietnam
(under the control of the Dai Viet from 1054 to 1804) where a river/estuary naval
battle took place in 1288 AD.

History of the naval battle at Bach Dang
Vietnamese historical records including Đại Việt sử ký toàn thư (Ngo 1993) and
An Nam chi luoc (Le 1961), as well as Chinese dynasty chronicles such as Yuan
Shi (Song 1976) mention the 1288 AD naval battle at Bach Dang. Later
historians, poets, and others have also written accounts of the battle (Trần 1963;
Hà and Phạm 1968; Nguyễn 1988; Phuong 2009:25; Lê, et al. 2010). Although
many accounts mention the battle, the real story is often shrouded behind myths
and legends. Detailed knowledge about the battle is limited due to the scarcity of
primary historical records. Therefore, since the 1950s and 1960s, it was realized
that a general study of the geology, geomorphology, inscriptions, legends and
archaeology was needed to more fully reconstruct the story of this event (Đại and
Diệp 1970:65).
In general terms, the history of the battle entailed the story that having
successfully taken the capital Thang Long (now Hanoi), the Mongol invaders
found themselves trapped in an empty city without supplies. They soon decided
2

�to abandon the capital and retreat, but the Dai Viet had decided to fight a
decisive naval battle with the invaders. The Vietnamese forces, under the
command of Tran Hung Dao and his generals, lay in wait for the invasion fleet
knowing that they would have to return to China through an estuary at the mouth
of the Bach Dang River. Tran Hung Dao was victorious and many of the Mongol
ships (perhaps numbering in the hundreds) were burned or lost during the battle.
The majority of historical sources agree that the principal tactic used by
the Vietnamese forces was to prevent the fleet from reaching the open sea and
trap them by using hundreds of secretly planted large wooden stakes that had
been sharpened to a point and driven into the riverbed at low tide (referred to as
stake yards). These stakes were probably covered at high tide and became
uncovered as the tide fell. This particular technique had also been used in the
area on two previous occasions in 938, when Ngo Quyen defeated the Southern
Han army, and in 981, when Le Hoan ordered stakes to be placed to block the
Song army.
The 1288 AD battle at Bach Dang River is widely considered to be a
milestone in the history of Vietnam as an independent nation and has shaped the
current culture of Vietnam. Tran Hung Dao is highly revered as the most able
general in the history of Vietnam. Since the battle, a number of shrines and
temples that worship Tran Hung Dao have been established, including in the Yen
Giang commune on Ha Nam Island. Some of these locations are related to myths
and legends associated with him. Some of these worship centers, such as the
Vua Ba Temple and the Trung Coc shrine, are large or well known (Phuong
2009) while others are much smaller and less well known. The religious aspects
of this research are important and the creation of the cult of Tran Hung Dao, his
many shrines, and his cultural impact and importance to Vietnam provide a
compelling contemporary aspect to the project.

Research up to 2005
Following the discovery of a large number of wooden stakes by local people in
the fields of Yen Giang commune (Quang Yen town), a group of researchers
from the Department of Conservation and Museums (now Department of Cultural
Heritage, Ministry of Culture, Sport and Tourism) went to Bach Dang in 1958.
They conducted a brief survey and opened three excavation trenches at the Yen
Giang site. Six stakes were found and it was believed that these were from the
1288 AD battle (Tống, et al. 1988).
In 1969 extensive survey and excavation was conducted by the
Department of History at Hanoi General University (now University of Social
Sciences and Humanities) in cooperation with local cultural officers (Đào 1969).
They excavated seven trenches covering an area of 520 meters squared (m2) at
the Yen Giang site and discovered another 32 stakes. Researchers studied the
soil profile, made a detailed examination of stratigraphy and concluded that the
area was an ancient riverbed (Đại and Diệp 1970:71-72). Then in 1976, a third
excavation was conducted at the Yen Giang site by staff from the Museum of
Vietnamese History. In addition to relocating the same cultural layer, several
3

�segments of wood were unearthed which were interpreted to be hammering tools
(Trần and Trịnh 1977).
In 1984, during construction of a dike along the Chanh River, more stakes
were unearthed, which were preserved in situ for future onsite exhibition by the
provincial authorities. In 1987 an extensive survey and excavation was
conducted by archaeologists from the Institute of Archaeology (IA) based in
Hanoi, in cooperation with experts from the Institute of Earth Sciences from the
Department of Conservation and Museums and local cultural officers. During this
fieldwork a survey of waterways and underwater rocks was conducted by canoe
along the Bach Dang, Chanh and Rut Rivers, and up to the Song Khoai area,
which was an ancient waterway and is now being used for aquaculture. The
researchers also made a general survey of the standing monuments, conducted
literature reviews and gathered oral histories of legends related to the Bach Dang
battlefield, and inscriptions and local knowledge about the tide to improve
understanding of the battlefield. Ten trenches were excavated in the Yen Giang
stake yard site and the stratigraphy was studied in detail in order to understand
the techniques used for inserting the stakes (Lê 1988; Nguyễn Công Thái 1988;
Tống, et al. 1988)
In 1995, during the digging of a fishpond, local people discovered several
stakes at Dong Van Muoi (DVM) site, which was already known to Vietnamese
researchers. The cultural officer of Yen Hung District took this chance to conduct
a test excavation (No any report so far, except the information of Mr. Lê Đồng
Sơn, Chief, Cultural sector, People‟s Committee of Yen Hung District, Quang
Ninh province). Finally in 2005, the Institute of Archaeology (IA) in cooperation
with the Department of Culture of Quang Ninh province conducted a survey and
excavation at the DVM site to identify the distribution and character of the site for
planning site conservation and protection (Lê and Hà 2005).

The current research
In May 2008 an international team of researchers from the Institute of Nautical
Archaeology at Texas A&amp;M University and the Maritime Archaeology Program at
Flinders University visited Vietnam to undertake an investigation of two wooden
anchors that had been found in the Red River near Hanoi (Sasaki and Kimura
2008). While in Vietnam the team also conducted a preliminary site inspection of
stake yards in the Bach Dang area, visited museums where stakes from the
battle(s) are held and met with Vietnamese researchers, including Dr. Vũ Thế
Long and Dr. Lê Thị Liên (IA). Also in 2008, a well-preserved new stake-yard was
discovered at Dong Ma Ngua (DMN) in Hung Hoc village, when a local resident
found large clusters of stakes while digging a fishpond.
In 2009, the Bach Dang Battlefield Research Group (the team) conducted
an extensive survey in Quang Yen town and on Ha Nam Island. They were also
asked by local cultural officials to map the stakes at DMN as well as to excavate
a small area to examine the soil profile (Figure 1).

�Figure 1. Dong Ma Ngua 2009, Jun Kimura in the mud of the fishpond indicating
the location of a stake for total station survey purposes (Photo by George
Belcher courtesy of the Bach Dang Research project).
The fishpond measured approximately 20 x 15 meters (m) and the team
recorded the location of 22 visible stakes. The distribution pattern of these stakes
appeared random at the time of the preliminary survey. In addition, a small trench
(1m x 2m) was excavated down to a depth of approximately 3m from the surface
of the fishpond. The majority of the stakes showed a remarkable state of
preservation and their surfaces appeared almost new. The profile of the trench
exhibited several layers indicating that a series of depositional events took place
in the past. The soil profile was characterized with a deep deposit of clay
overlaying a deposit of sand, which indicates a typical estuary or a shallow river
gradually filling in. Considering the well-preserved nature of the wood, recent
depositional events may have occurred at a relatively fast pace (Lê et al. 2009;
Sasaki 2009). One of the principal research questions for this project has been to
establish accurate dates for the stake yards, which involves a program of
radiocarbon dating of samples from the stakes. Five wood samples from isolated
stakes were collected for Carbon 14 (C14) analysis and species identification.
The results of C14 analysis provided a date range around 700 years Before
Present (BP) that was in accordance with our expectations.
In 2010, fieldwork continued at the DMN site with four new trenches
opened that were later integrated into one large trench (Figure 2). Two additional
test trenches were opened in the rice fields around the DMN site to compare the
sediments in the surrounding area and to further develop our understanding of
the topographical features. As a result of the excavation, 55 stakes (plus one oar,
other wood fragments, potsherds and ceramics) were identified in the fishpond.
The position of these stakes and some important topographical features around

5

�the site were recorded and photo mosaics of the site were also produced (Kimura
and Pham 2010; Lê 2010).

where 25 stakes were identified, photographed, analyzed and from which wood
samples were extracted. The stakes diagonally driven are facing each other.

project).
The 2010 fieldwork season focused on recording the stake distribution
pattern. The stakes were aligned in columns, orientated in various directions. It
appears that two sets of columns were driven to face each other at the upper
ends of the stakes. Some of these stakes were also driven densely to form a
wall-like feature. Similar diagonally driven stakes had also been seen in the
previous excavated stake yards (Le and Ha 2005). Although the original
dimensions of each stake are difficult to ascertain due to their deteriorated
condition, the diameters may fit to some regular range of approximately 6
centimeters (cm), 12cm, or 20cm. The bottoms of the stakes were observed and
some of them had a recess or a notch. Although this feature could not be
confirmed on all stakes, it appears that they might have been associated with the
method used to set the stakes in place. Yet, the way the large stakes were set
into the riverbed is still under debate.
Wood samples from ten stakes were sent to Forestry and Forest Products
Research Institute in Japan and the University of Forestry of Vietnam for species
6

�identification. They were identified as Meliaceae sp. (họ Xoan) or Rutaceae sp.
(họ Cam/Chanh), and another was Leguminosae sp. (họ Đậu) The remaining
samples were Shorea-Shorea (Dipterocarpaceae sp 3 samples) (họ Sao
dầu),Peltophorum dasyrachis (lim xẹt or hoàng linh in Vietnamese), Parashorea
chinensis (chò chỉ), Lithocarpus ducampii (dẻ đỏ), Dipterocarpus tonkinensis
(chò nâu), and Engelhardtia roxburghiana sp (chẹo tía). Legend suggests that
ironwood was used for these stakes and the term ironwood can be interpreted as
any hard, dense wood, which seems to correspond well with the results of the
species identification.
Through the analysis of soil profiles, it seems that the local topography at
the time exhibited a significant change in elevation with stakes driven into the
slopes of channel banks. At DMN the riverbank appears to have sloped from
east to west, which was deduced from the 1m difference of elevation that exists
between the stakes found in east and west trenches within the same sediment
layer. The sediment includes a number of thin layers, which resulted from river
deposition processes. The sediment changes from top to bottom, from clay, clay
with sand, sand, and finally sandy silt. Some layers were subdivided by subcontexts, such as tiny clamshells, large oyster shells, and degraded plant
remains. According to Doan Dinh Lam (pers. comm.), a Vietnamese geologist,
these are typical river sedimentations observed in the area; the clay in the upper
layer confirms that it results from a lesser tidal influence and from slow
sedimentation. In the lower layers, however, some of the sand layer and sandsilt layer exhibit much thicker deposit. The thick layers are identified as original
riverbed into which the stakes were driven.
A large number of artifacts were excavated, including the stakes and
wooden fragments, pottery (ceramic and stoneware), bricks and tiles. A broken
oar most probably associated with a small boat has been unearthed (Figure 3).
Several small wooden artifacts have been interpreted as wooden tie rods. Some
fragments have processing marks, such as rope holes for transportation or
probably mortised holes. The flatness of some fragments suggests that they
could be manufactured woodwork rather than stakes. Thus, it is possible that
fragments of boats or ships have been found in this area. A large amount of
degraded wood fragments and charcoal and a thick layer of blackish silt were
observed in the excavated area, which indicates the use of firing.

�The pottery fragments represent a wide range of dates (13th to 18th
centuries), and includes both (earthenware?) ceramic (28 fragments) and
stoneware (79 fragments). Ceramics analysis is currently ongoing but some of
the ceramics are dated to the Tran Dynasty (1225-1400), including the whitish
glazed and cracked brown glazed ceramics of the 13th-14th centuries and the
blue-and-white ceramics of the 15th-17th centuries. Some of the ceramics were
found in the same sediment layer as the stakes, and some were found in the
layers above. Although their location might have been disturbed due to the
flowing waterway, it was noticed that fragments of ceramics and stoneware
datable to 13-14th century and 15th-16th century have been found mainly from
the sandy clay layer (layer 3) and clayish sand layer (layer 4). A fragment of
Chinese Song celadon was also unearthed from layer 4. Layers 3 and 4 are
proposed to have been the riverbed during the 1288 AD Bach Dang battle (Le
and Nguyen. 2011).
Vietnamese researchers previously calculated the tide-fluctuation levels
they occurred on 8th March 1288 (Nguyễn Ngọc Thụy 1964:36; Nguyễn Duy Hinh
1988). The stratigraphy at the DMN site suggests that the riverbed in this area
was at a depth of about 5.2-5.5m during the highest tidal level and 3-3.2 m at the
lowest one, according to modern tidal levels)3. If stakes more than 3m long were
driven into the riverbed, the Mongolian ships, which have about 2.5 m of
waterline4 would not have been able to cross this area.

Conclusion
Each of the monuments, stake yards, and the ancient topography that lies hidden
beneath the modern landscape of the Bach Dang Battlefield in Yen Hung district,
Quang Ninh province reveals a part of the Vietnamese strategy to defeat the
Mongols. There are 3 major stake yards where the distribution, nature and
dimensions of the stakes have been identified and recorded: the Yen Giang, the
Dong Van Muoi (DVM) and the Dong Ma Ngua (DMN) sites. It first appeared that
the stakes might have been placed between the ancient islands and navigational
hazards in order to create an effective „wall‟ preventing the vessels from travel
through the channels and into the open sea. This was deduced from the
positions of the stake yards sandwiched between natural hazards (Figure 4). The
excavations at the DVM and DMN sites, however, seem to suggest that it was
not a simple wall that the Vietnamese created. When constructing such a wall
around the waterways and islands, one must also consider how to prevent the

Nguyen Duy Hinh (1988) used the 1971 data of Do Nghi Gauging station to suggest that in the
th
8 March 1288 of the Lunar calendar, the highest tidal level was 1.52m and the lowest one was 1.43m. From the datum point set up by the Bach Dang research team in DMN site, the riverbed
from excavated pit H3 is about - 3.2m deep. According to Mr. Le Dong Son (Chief of Culture
Bureau, Yen Hung district), without the dike system, during the height tidal level, tidal flow may be
more than 2m above the datum point.

�enemy from landing and taking control of the land. As a result, a more complex
arrangement of stakes may be expected.

There was an ancient waterway in the excavated area at DMN that had a
higher bank in the eastern side and was gradually silted up, as indicated by
layers of sandy silt and alluvium. The land changed from an estuarine salt-marsh
to brackish swampy area as indicated by the presence of several types of teredo
(worm) of various species and sizes. The result of pollen analysis for the DMN
site provides evidence of flora in this area, including arboreal, shrub and nonarboreal plants, fern spores and especially a diversity of mangrove plants.
Generally, although this area was always affected by sea tides, the influence was
not the same throughout history of its sediment formation, as indicated by the
presence of an abundance of mangrove pollen. Based on the ecological
characteristics of various types of mollusks, we can also see the change from
directly affected by the sea - to tidal mangrove estuary environment (Nguyễn, et
al. 2011).
Further survey work is planned for late November 2011. A remote sensing
survey, core sampling and limited test excavations will be conducted to find more
stake yards as well as possible shipwrecks. Stake yards are expected to be
buried below several meters of silt and to be in excellent condition, preserving
the original configuration of the stakes.

                <text>The Mongols created the worldâ€™s most powerful empire in the thirteenth century, conquering China and establishing the Yuan dynasty. Their military power was in doubt, however, after failed naval invasions in Japan and Vietnam. According to historical records, the Vietnamese tactics used against the Mongolian Armada were designed to prevent them from reaching the mouth of Bach Dang River by using hidden stakes that were driven into the riverbed in secrecy. Using the large difference in tides, the Vietnamese successfully lured the enemy fleet into the trap, destroying or capturing perhaps as many as 400 vessels. Since the 1950s, approximately 700 years after this watershed event, Vietnamese archaeologists have discovered a number of large wooden stakes in the midst of reclaimed paddy fields along the Bach Dang River. Excavations and research were conducted which led to the identification of several stake-yard sites believed to be dated to the battle that took place in 1281 C.E., however, no remains of ships have been identified to date.&#13;
&#13;
In 2009, a group of scholars from the Institute of Archaeology at Hanoi, the Institute of Nautical Archaeology at Texas A&amp;M University, and the Maritime Archaeology Program at Flinders University joined the archaeological investigations of these stake-yard sites with a focus on studying the battle strategy used by the Vietnamese and identifying ship remains from the battle. This joint paper will present an intermediate result of this international cooperative project in maritime archaeology in Vietnam at the naval battle site related to the thirteenth century Mongolian invasion of the country. The team has identified several new areas of concentrated stakes and the distribution pattern may lead to better understanding of the battle and the possible location of shipwreck sites.</text>

                <text>The awareness of protecting the Underwater Cultural Heritage (UCH) has grown over the past decades around&#13;
the world as well as in Taiwan. In-Situ preservation is the international principle of management and&#13;
protecting the site. Following the UNESCO 2001 UCH Convention, Taiwan passed the Underwater Cultural&#13;
Heritage Preservation Act in 2015. Since then, there have been 6 listed shipwrecks and over 90 potential&#13;
targets were found by the underwater archaeology team of Academia Sinica. Different approaches in each&#13;
sites’ management depend on the environment and material such as wood, metal or even bones, and as the&#13;
result, a practice of setting up an environmental database, implementation of a regime of regular underwater&#13;
observation by divers or unmanned underwater vehicles, and oceanic dynamic monitoring should be adopted.&#13;
In 2020, despite many difficulties, a research project focused on these related issues for scuba diving&#13;

ABSTRACT
To better identify submerged archaeological targets, multiple state-of-art survey techniques were carried out in
underwater geoarchaeological studies at the exploration stage. Previous underwater surveys identified ten Dutch
colonial vessels dating from the first half of the seventeenth century. Four of them were found on the banks of the
Yanshui River, and most of them were situated at the historical waters of Dayun Port. Underwater archeology
research at this inland sea of Tainan, the base for the Dutch route, was the key era in the development of maritime
trade in Southeast Asia. Therefore, inspecting the potential archaeology in Taijiang Waters is under our
consideration, which is situated in a historical city, Tainan, leads us to link the ancient shipwreck event to consider
the sustainable preservation solution.
However, it is challenging to inspect the submerged archaeological targets since the geomorphology
rapidly changed due to the long- and short-term geological processes. The resources available to conduct the work
include accurate frequency control on magnetic data acquisition and comprehensive geophysical integration for data
interpretation. Therefore, we combine the acoustic and magnetic techniques and joint airborne and shipborne
geophysical surveys to inspect the submerged assessment. After integrating with previous survey results, seven
underwater cultural heritages were linked to shipwrecks, which allows us to embark on follow-up verification plans
for archaeological research, preserving the potential historical footprints of Taiwanese and the treasure wetlands
environments of the Taijiang National Park for endangered ecosystems.

INTRODUCTION
The topic of this paper fits best within this Session 24 ‘” Database, monitoring, non-intrusive
documentation techniques and new technologies applied to underwater cultural heritage” because we
jointly apply multiple the-state-of-art survey techniques including airborne- and shipborne-based
geophysical methods to inspect the submerged archaeological sites in the Taijiang Waters of Taiwan.
Overall, this study is based on non-intrusive geophysical methods and it involves database building and
future underwater cultural heritage (UCH) monitoring/preservation.
The Taijiang Waters are archaeologically significant since it was a crucial ship channel during the
seventeenth century and therefore many ships sank in its surrounding waters during the period. Previous
studies have found at least ten Dutch vessels in the study area dating from the first half of the seventeenth
century (Chiang, 1999; Li, 2018; Wang, 2012). However, it is challenging to inspect the submerged
archaeological targets by using traditional surveying methods due to the poor visibility in the water, strong
tidal currents, and rapidly changing morphology. For instance, the strong tidal currents can be dangerous
to divers and the low water visibility makes it difficult to operate underwater cameras. Moreover, the
1

�rapid erosion and deposition processes cause major challenges in monitoring, or even locating the
archaeological targets. Please note that many land or wetland areas were oceans back in the seventeenth
century due to the massive sediment deposition carried by the Yanshui River. This results in limited water
areas nowadays capable of ships or boats passing through.
With all the restrictions and challenges, this study also applies airborne-based geophysical survey
methodology to acquire the overall information within the study area, including the land areas or fish
farms where shipborne-based methods cannot be operated. A more detailed description of the geophysical
instruments used is outlined in the “Resource” section. By integrated analysis of various geophysical data,
we have built a database and developed a workflow for locating and monitoring the potential
archaeological targets, which may give insights into the surveying strategies in other shallow water areas
worldwide that are challenging for applying traditional archaeological surveying methods.
CASE STUDY
The case studies under consideration mainly are the previous geophysical surveys used for shallow water
UCH identification. According to the previous experience, we realized that a new and integrated approach
must be introduced to overcome the environmental challenges in Taijiang Waters.
Geophysical prospecting methods have been extensively used to locate buried antiquities in terrestrial
sites for decades. This approach involves interdisciplinary studies which is also applicable and efficient
to document the underwater environment in detail. Besides mapping the subsurface images, geophysical
prospecting methods also provides critical physical properties of buried structures to complement
archaeological research in a timely and costly efficient manner. The technological and methodological
innovations upgraded it from an “amateur” activity to scientific research with a substantial contribution
in the domains of past commerce and coast exploitations (Dobson 2005). However, the coastal and
shallow underwater areas are still considered a “gray zone” or “white zone”, where different factors create
a unique, constantly evolving, and challenging environment, sharing elements from both deep- water
investigations and dry land surveys, which neither the equipment for deep-water exploration nor those
used for dry land surveys can be directly employed in coastal areas (Galanidou, et al. 2020).
Generally, most of the efforts to reconstruct the hidden cultural heritage are mainly focused on deep-water
environment explorations by acoustic geophysical methods that have been used to map ancient
shipwrecks (Sakellariou, et al. 2007). The accessibility of shallow water archaeological sites rise a
dilemma for the government, as it must decide whether to prioritize openness to the public or protect
cultural assets. On the other hand, the water presence in submerged lands makes this area susceptible to
various post-depositional or abandonment effects, as evidenced by the Taijiang Waters in Taiwan (Li
2018; Wang 2012). Perhaps that’s the reason why there is no coherent and efficient approach or technique
so far for shallow-water heritage documentation, study, and protection, despite the availability of methods
to investigate the cultural heritage in dry land or deep water (Papadopoulos 2021).
Since October 1966, several archaeological targets including a wreck site were discovered in the marine
environment of Akko Harbour using a proton magnetometer, the technique has been widely used for
underwater cultural heritage (Arnold and Clausen 1975). Today marine proton magnetometers have
largely been replaced by optically pumped cesium vapor magnetometers and Overhauser effect
magnetometers, both of which provide greater sensitivity and much faster cycle rates (Green 2014).
Nevertheless, magnetic surveys may effectively detect shipwrecks but require a proper design operating
in good weather conditions. And the beauty of a magnetic survey is that we don’t need to submerge the
magnetometer before it can detect a shipwreck, most accessible wrecks that lie in shallow waters (&lt;30m)
are detectable from the surface (Steenkamp 2017). Generally, shipborne surveys are used for searching
for wrecks in shallow waters and may be complemented by cheaply available side-scan sonar equipment.
In Taijiang Waters in Taiwan, where some areas are difficult for the boat to access, we intend to take the
advantage of a small drone equipped with a fluxgate magnetometer to offer good values to inspect the
2

�submerged archaeological sites.
The sediment deposition in the Taijiang Water has greatly impacted human activities (Chen and Chang
2010). In the 17th century, the Taijiang Water was a natural port and was the administrative, economic,
and cultural center of Taiwan. However, due to the sediment infill process of the Taijiang Water, it became
more difficult to navigate ships in the nineteen century, and eventually impossible for the ships to pass
today. Figure 1 shows an example of the Taijing coast in the seventeen and twenty-first centuries. Due to
the severe sediment deposition processes, numerous coastal communities that depended on shipping for
their livelihood have declined.
To investigate the UCH in the Taijiang Waters, the Taiwanese government has conducted a shipboard
general geophysical survey, including a multibeam echo sounder (MES), side scan sonar (SSS), subbottom profiler (SBP), and magnetic surveying (MG) (Lai 2018). Based on these datasets, several potential
UCH targets were identified. After that, they conducted a detailed survey including underwater
photography and resistivity image profiling, in addition to the four methods used in the general survey, to
examine potential UCH targets. However, during the detailed survey, they observed a significant
topographic change caused by rapid sedimentary processes. Either moving by the currents or buried by
sediments, numerous previously identified potential UCH sites showed no obvious geophysical anomalies
from the data collected from the detailed survey. Therefore, this study aims to introduce a joint data
analysis technology to better detect and monitor potential UCH targets in this challenging site.

RESOURCES
To better identify the submerged archaeological targets (potential UCH) in Taijiang Waters, we integrated
multiple the-state-of-art survey techniques to improve the certainty of potential target recognization. Our
survey strategies and techniques in Taijian underwater geoarchaeological research not only increased the
3

�density of the ship tracks to better image the seafloor topography, and profile the subsurface strata and
magnetic features to recognize the potential targets; but also, we take the advantage of magnetic anomalies
derived from airborne and shipborne geophysical surveys, to inspect the assessments which might be
buried in the subsurface. Furthermore, we directly sample the channel sediments to investigate the
sedimentological and environmental records to study the potential geological events in hundreds of years.
The instruments and survey strategies we used are introduced as follows.
Shipborne-based geophysical survey
Based on the existing water depth and nautical chart data, the investigative scope of the Taijiang Waters
includes intertidal zones with water depths ranging from 0 to 10 meters. Due to the shallow water depth
and numerous obstacles such as oyster rafts near the coast, the operation uses a small boat, the Wan Bao
Long 58, to reduce operational risks. The vessel has a total length of 14.60 meters, a width of 2.90 meters,
a maximum draft of 0.74 meters, and a total tonnage of 11.75 tons.
(1) Side-scan sonar (SSS)
We use an EdgeTech 4125 side-scan sonar to collect dual-frequency seafloor images for the entire area
while the survey line spacing and instrument's slant range were set at 25 meters, simultaneously.
(2) Multi-beam bathymetry (MB)
We predominantly use the RESON SeaBat 9001 multi-beam sounder with a survey line spacing of 10
meters to collect the bathymetry data. For the areas with water depth shallower than 1 meter, the Odom
Echotrac CV100 single-beam sounder was used to fill the gap. Besides the relevant position, the angle
deviation was obtained by superposition testing. All data were recorded in the collection software to
obtain the relative position parameters of the instruments in 3D. For the sound velocity information, the
vertical sound profile was measured at least 2 times a day. More measurements were conducted with
significant changes in water temperature or salinity.
(3) Sub-bottom profiler (SBP)
We utilize the EdgeTech SB-216S tow-fish with a digital variable-frequency sonar sounder in 10 meters
line spacing survey to image the subsurface strata.
(4) Magnetic Survey (MG)
Considering of the interference of the vessel, the SeaSPY used for shipborne magnetic survey was
tied to a float and towed about 30 meters behind the vessel. And principally we set up the line space
as 12.5 meters to derive better coverage of the data.
Airborne magnetic survey
With the airborne magnetic survey, we undertook a general survey around the Taijian area with 100%
coverage and a detailed survey focussed along the river to better detect anomalies in those waters.
(1) General Survey
The general survey aims to mark the distribution of buried magnetic bodies. The operation height should
be adjusted according to the environmental conditions. Therefore, a 25-meter design line spacing is used
for this phase of the survey. The measurement height is set between 15-20 meters above ground level and
adjusted according to the height of buildings, power poles, or windbreak trees in the survey area.

�(2) Detailed Survey
Ideally, the survey line spacing is about 4 meters with a flying height of 4-8 meters above the
ground/water level. The actual survey area was selected based on the results of the general airborne
magnetic survey and the shipborne geophysical surveys.

FRAMEWORK
This study aims to identify potential UCH targets by applying geophysical methods for future monitoring
and preservation. Considering the challenging survey environment, we applied an integrated analysis of
different geophysical datasets including the MB, SSS, SBP, and magnetic methods.
In terms of geophysical data interpretation, the exposed targets were mainly identified through the
interpretation of the SSS images. All the exposed targets show magnetic anomalies. However, due to the
poorer resolution of the multibeam terrain data, the comparison results between exposed target objects and
multibeam data target objects were inconsistent, and their shapes could not be identified through the
multibeam depth data in this area. As fishing activities are prosperous in the Taijiang Waters, there are
many oyster rafts or abandoned fishing gear in the river channel. Therefore, anomalous responses observed
only from one single geophysical data were not used as the basis for identifying potential UCH target
objects. Regarding the buried target objects, anomalous responses observed from SBP and magnetometer
are the main criteria for interpretation.
After the integrated geophysical data analysis, we compared the potential UCH target locations with
historical literature to have a preliminary idea from an archaeology perspective.

RESULTS
Besides collecting shipborne geophysical data including the SSS, MB, and MG, we further check the
subsurface feature by SBP to define the suspicious targets (Figure 2). Then we combined the magnetic
anomaly derived from airborne and shipborne geophysical surveys simultaneously to inspect the
submerged assessment (Figure 3), the resources available to conduct the work include accurate frequency
control on magnetic data acquisition and comprehensive geophysical integration for data interpretation.
After integrating and interpreting various survey data in the Taijiang Waters, a total of 13 potential UCH
targets were obtained (Figure 4), including 12 targets on the riverbed and 1 buried target. With these
results, we are confident that our strategy of jointly analysing multiple geophysical data can increase the
chance of identifying potential UCH sites and therefore benefit geoarchaeological research.
After integrating with previous survey results, seven underwater anomalies were correlated to the ancient
Dutch shipwreck (Figure 4). This allows us to now embark on planning follow-up verification of each
anomaly through archaeological research, for the purposes of confirming, or not, discovery and
identifying each site. Through these activities we hope to preserve the historical underwater cultural
heritage of the Taiwanese, and the endangered ecosystems of the treasured wetlands environments of the
Taijiang
National
Park.

                <text>To better identify submerged archaeological targets, multiple state-of-art survey techniques were carried out in&#13;
underwater geoarchaeological studies at the exploration stage. Previous underwater surveys identified ten Dutch&#13;
colonial vessels dating from the first half of the seventeenth century. Four of them were found on the banks of the&#13;
Yanshui River, and most of them were situated at the historical waters of Dayun Port. Underwater archeology&#13;
research at this inland sea of Tainan, the base for the Dutch route, was the key era in the development of maritime&#13;
trade in Southeast Asia. Therefore, inspecting the potential archaeology in Taijiang Waters is under our&#13;
consideration, which is situated in a historical city, Tainan, leads us to link the ancient shipwreck event to consider&#13;
the sustainable preservation solution.&#13;
However, it is challenging to inspect the submerged archaeological targets since the geomorphology&#13;
rapidly changed due to the long- and short-term geological processes. The resources available to conduct the work&#13;
include accurate frequency control on magnetic data acquisition and comprehensive geophysical integration for data&#13;
interpretation. Therefore, we combine the acoustic and magnetic techniques and joint airborne and shipborne&#13;
geophysical surveys to inspect the submerged assessment. After integrating with previous survey results, seven&#13;
underwater cultural heritages were linked to shipwrecks, which allows us to embark on follow-up verification plans&#13;
for archaeological research, preserving the potential historical footprints of Taiwanese and the treasure wetlands&#13;
environments of the Taijiang National Park for endangered ecosystems.</text>

ABSTRACT
The topic of this abstract fits best within this Session 12 because the study aims to investigate the
potential of digital technologies in promoting the cultural heritage of Stone Tidal Weirs, also known as
"Stone Tidal Weirs" in Taiwan. The Stone Tidal Weirs are an integral part of Taiwan's history and
culture, yet their significance is often overlooked. This study aims to address this by utilizing digital
technologies to raise awareness about Stone Tidal Weirs and their cultural significance, as well as the
ecological
significance
of
the
Stone
Tidal
Weirs
in
near-shore
ecosystems.
A mobile application, Poket Xinwu, was developed in collaboration with local communities and
university groups to ensure the authenticity and accuracy of the information provided. The app features
interactive content that allows users to learn about the Stone Tidal Weirs and their surroundings in an
engaging and intuitive way. Additionally, the app aims to raise awareness about the environmental issues
surrounding Stone Tidal Weirs and the importance of preserving the local ecosystems. The app also
serves as a tourism promotion tool, encouraging visitors to explore the Stone Tidal Weirs and learn more
about
marine
culture.
The study found that the app game was successful in promoting the cultural heritage of Stone
Tidal Weirs and raising awareness about their significance. The app's interactive content and the
collaboration with local communities were identified as key factors in its success. The study concludes
that digital technologies can be effectively utilized to promote and preserve cultural heritage and can
foster collaboration and understanding between local communities and visitors.

INTRODUCTION
The topic of this abstract fits best within this Session 12 because the study aims to investigate
the potential of digital technologies in promoting the cultural heritage of Stone Tidal Weirs,
also known as "Stone Tidal Weirs" in Taiwan.
Dr. Asahitaro Nishimura, a maritime anthropologist and a leading authority on the study of
Stone Tidal Weirs, referred to this traditional fishing equipment as a "living fossil of the oldest
fishing gear," believed to be the world's oldest. (Nishimura 1969; Nishimura 1979). Fish traps
are one of the most widespread and enduring features of the maritime landscape. And research
also in Ireland has identified a great number of traps, most of which date from the early to late
medieval periods (Montgomery, Forsythe &amp; Breen 2015).
Stone Tidal Weirs were once widely distributed in coastal areas with remarkable tidal action
and coral reef areas with developed lagoons throughout the world. Figure 1 shows the areas in
which Stone Tidal Weirs were distributed (Tawa 2007).

�Figure 1 Distribution of Stone Tidal Weirs in the World (Tawa 2007)

In the latter part of the 1980s, geographers in Taiwan conducted a survey of Stone Tidal Weirs,
including the author's study of those located along the northwestern coast of the main island.
In the 1990s, extensive research was undertaken on Stone Tidal Weir fishing in the Penghu
Archipelago, with active involvement from researchers, local school teachers, and their
students (Chen 1992;1996). More recently, research has focused on a complete census of Stone
Tidal Weirs, providing valuable insights into the cultural heritage of Taiwan and clarifying the
use of fishing villages and grounds in the Penghu Archipelago (Hong 1999).
The Stone Tidal Weir is constructed on seaward slopes or fringing reefs, and comprises a semicircular or horseshoe-shaped wall built from stones or coral lime stones. Its design is closely
linked to tidal changes, with fish swimming or being swept into the weir during high tide but
unable to escape during low tide. The fish are then caught in the shallow water within the weir
using small push nets or dip nets. The Penghu Archipelago in the Strait of Taiwan is home to
over 500 Stone Tidal Weirs, the highest concentration in the world, while the western coastal
region of the main island also has a significant number of weirs, with some still in use today.
In Taiwan, the Penghu Archipelago in the Strait of Taiwan is the region with the world’s largest
concentration of Stone Tidal Weirs, with over 500 weirs in total. The western coastal region of
the main island is another area where a large number of weirs were once distributed, with some
remaining today (Tawa 2010).
The Stone Tidal Weirs are an integral part of Taiwan's history and culture, yet their significance
is often overlooked. This study aims to address this by utilizing digital technologies to raise
awareness about Stone Tidal Weirs and their cultural significance, as well as the ecological
significance of the Stone Tidal Weirs in near-shore ecosystems. The Stone Tidal Weirs form
art and game exploration narratives which virtually experienced many of these traditions in
indigenous community of the region.

CASE STUDIES
The case studies under consideration are the following. The research background of
this study originates from the team's discovery of the Xinwu's Stone Tidal Weirs in
2017. The structure of the Stone Tidal Weirs and its significant role in the lives of
coastal residents fascinated the team, and led to the conception of a 'coastal library'.

�After conducting multiple visits and interviews with local residents, the team learned that the
local community has made several attempts to preserve and promote the culture of Stone Tidal
Weirs. These efforts include developing environmental tours, organizing community events,
and promoting extended local specialties. However, the irregular frequency of events, the need
to consider tidal conditions for activities, and the natural seasonal limitations along the coast
have proven to be major obstacles. Therefore, this study aims to address these limitations by
focusing on Xinwu’s Stone Tidal Weirs, the largest and most well-preserved area on Taiwan's
mainland, with 9 Stone Tidal Weirs completely according to the Taoyuan City Government
Marine Engineering Bureau (Office of Coast Administration Construction, Taoyuan 2023). The
study's objective is to promote the culture of the Stone Tidal Weirs through a digital app
platform, eliminating human, environmental, and seasonal factors. Moreover, by collaborating
with the local community during the production process, this study seeks to develop a more
comprehensive
understanding
of
the
Stone
Tidal
Weir’s
culture.
1. Project planning and team recruitment: Xinwu People's Association collaborated with the
local enterprise Tempest Digital Co., Ltd. to plan the development of the Poket Xinwu app. A
student development team was formed by recruiting interested members from National Central
University's Game Creator Club.
2. Research and data collection: The main interactive teaching tool used in the Poket Xinwu
app was the No. 1 stone weir (Figure 2). To better present the actual characteristics of the stone
weir in the app, multiple visits and data collections were conducted with the community. The
community also took the team to repair the stone weir and explained the architectural structure
of the heart-shaped six-stone weir. The stone weir was built in the 13th year of the Qing Dynasty
and was an arc-shaped weir with many oysters and shells attached to the stones that form a fishdragon shape. It was not listed as a national cultural heritage site until 2013 (Taoyuan City
Government Cultural Affairs Bureau, 2019). Currently, the stone weir is continuously repaired
and patrolled, and the local area is mainly engaged in agricultural production with fishing as a
supplementary activity.

Stone Weir, with association members providing guidance to a game maker on the repair process (bottom).

3. Feature extraction: To develop the Poket Xinwu app (Figure 3), the cultural features of the
stone weir were extracted. After understanding the basic architecture and history, the app
mainly focused on two directions as the main features: ecological features and surrounding
attractions. The unique fish and ecological environment of the New House Stone Weir were
locked as the ecological feature. Common fish names and photos found in the stone weir were
collected through several visits to the local community and on-site inspections (Figure 4). The
fishing scenes of the stone weir were restored as much as possible. Surrounding attractions
were identified as another key feature. As the New House Stone Weir is a connecting point for
the whole community, surrounding attractions were identified along the coastal and inland
areas. Members of the New House Love Township Association were interviewed, and field
visits were conducted to identify unique local attractions.

4. Game mechanics: The Poket Xinwu app's gameplay is based on the story of sister Jiang
Mina returning to New House to assist her father's business. By managing attractions, new
surrounding attractions are unlocked. Each attraction unlocks various rewards, and players
progress through the game by collecting rewards and managing the business successfully.
In this study, we developed an app to promote the ecology and history of stone water. Before
the app's development, we did not have a complete compilation of information on the fish
5

�ecology in Stone Tidal Weirs. However, after the app's development, we successfully created
a fish map of Stone Tidal Weirs. We put it into the Stone Tidal Weirs Storytelling Museum to
introduce the ecology, which is an important function of the app that allows users to understand
more about the ecology and history of Stone Tidal Weirs.
Before the app was created, the local association used tours and excursions to protect and
promote Stone Tidal Weirs. However, in the course of the app, we found that more and more
people joined the app and began to describe their impressions of Stone Shanghai and their
memories of the past, such as the aunt who collected sea melon seeds and vegetables and the
uncle who collected driftwood for carving, which reflected the important role of the Poket
Xinwu app in promoting the culture of Stone Tidal Weirs. In addition, we found that the ecocircle1 of the Stone Tidal Weirs-community is known and promoted after the production of the
Poket Xinwu app. This shows that the app we developed has successfully contributed to
transmitting and promoting Stone Tidal Weirs culture.
The number of visitors to the experience of high school students in using the app show that the
app has good experience and promotion benefits. For example, a student pointed out that the
app cooperated with local merchants to launch coupons to promote tourism. In addition, the UI
of the app is quite simple and easy to use, and there is no problem with cards or unpleasant
operations. In addition, we noticed that some students, generally rated the app highly, saying
that it was good and had an important role in promoting Stone Tidal Weirs culture. On the other
hand, some students suggested that the game would be more enjoyable if it could be presented
in a non-idle format to increase interactivity.
In conclusion, the Stone Tidal Weirs app developed in this study has achieved positive results
in promoting Stone Tidal Weirs culture and promoting Stone Tidal Weirs ecological protection
and has promotional benefits and good usage experience.

the marine ecology, field surveys of nearby attractions, and a wealth of community data and
relevant documentary sources.
The development of the interactive mobile application involved the use of Unity software, the
collection of artistic materials, and the creation of a script for the storyline. In addition, a large
number of interviews were conducted to align the storyline of the mobile application with the
cultural significance of Xinwu People’s Association. The application called Poket Xinwu app
was published on Google Play, which allowed for analysis of downloads and market feedback,
giving us insights into user backgrounds and qualitative evaluations. Since its release on March
27, 2021, the Poket Xinwu app has received a total rating of 4.4 stars on Google Play as of
April 5, 2023. The app has had an average distribution of downloads over time, with a total of
207 installations and 151 uninstalls. The current user retention rate is 27%. The app also
features a mechanism for providing discount coupons to local shops, which some users have
already redeemed. These insights into user behavior and feedback from the Google Play
platform can help inform future updates and improvements to the app.
The collaboration between the research team and the local community proved to be an
indispensable resource in achieving a co-creation of knowledge and a deep understanding of
the cultural significance of Xinwu People’s Association. Through this fruitful partnership, we

�were able to identify and prioritize research questions, and to develop a comprehensive research
plan that effectively met the needs and aspirations of the local community.
Direct access to the local marine management agency through government-sponsored activities
provided us with crucial information on the Stone Tidal Weir’s culture and surrounding scenic
spots. Additionally, we gained valuable insights into the government and local community's
perspectives, goals, and plans regarding Stone Tidal Weir culture and the site's management.
The local association has adopted a cautious approach that prioritizes the preservation of the
local ecology, which allows for limited tourism to avoid coastal waste and damage to the stone
weir. In contrast, the government supports sustainable commercial applications that aim to
efficiently manage and promote the site while catering to the needs of a large number of tourists
interested in understanding Stone Tidal Weir's cultural ecology.
During our research process, we observed that developing an application that promotes and
protects the culture of Stone Tidal Weir is in line with the positions and needs of both parties.
The consensus framework2 for this proposal proved to be highly conducive to the successful
promotion and preservation of Stone Tidal Weir. Our findings highlight the importance of
effective collaboration between research teams and local communities, especially in preserving
culture and promoting sustainable development.
Xinwu People’s Association and the nearby marine ecology were important resources that
provided us with a unique research opportunity. Xinwu People's Association is a local
organization in Xinwu that is dedicated to the protection and promotion of Stone Tidal Weir
culture, and the marine ecology in the area is diverse and complex. These resources allowed us
to study the historical and ecological significance of the area and gain a deeper understanding
of the cultural and natural heritage of the community.
Field surveys of nearby attractions provided us with additional resources for our research. We
conducted surveys of nearby tourist sites to understand their impact on Xinwu People’s
Association and local communities. This allowed us to identify potential threats to the site and
the community and develop recommendations for sustainable tourism practices.
Finally, a wealth of community data and relevant documentary sources allowed us to stay upto-date with the latest research developments and incorporate this knowledge into our work.
We collected and analyzed global articles related to Stone Tidal Weirs and integrated this
information into our research, providing a broader perspective and deeper understanding of the
significance of Stone Tidal Weirs.

FRAMEWORK
The research problem is the marketing and promotion of the stone tidal weirs is insufficient. In
the past, the promotion of stone weirs was mainly through academic research and event
organization. As a result, the general public's understanding of stone weirs is insufficient, and
with the changing times, the number of users of stone weirs has also decreased. Therefore, to
address the problem of insufficient promotion of stone weirs, this study employs game base
marketing to develop an APP game to help the public learn about and virtually experience the
culture of stone tidal weirs.

RESULTS (expected)
In the past, the promotion of stone fish weirs was mainly through academic research and
physical activities. By creating an app game-based marketing, the cultural significance of stone

�fish weirs can be easily promoted. In the future, this can be combined with LINE application
for digital marketing and the establishment of a virtual world Stone Fish Weir Museum.
The United Nations Environment Programmed released a report titled "War and Environment:
Destruction, Pollution and Recovery" in November 2021. The report states that the destruction
and damage caused by war and armed conflict to the environment and ecosystems has reached
unprecedented levels, and that these damages will have long-term effects on local and global
environments and human health. The report proposes solutions such as strengthening
international legal frameworks, protecting cultural heritage, and supporting sustainable
development. By promoting and preserving the data of stone fish weirs through an app game,
we can prevent the loss of cultural information caused by destruction during war and armed
conflict.

CONCLUSION
To conclude, the study found that the app game was successful in promoting the cultural
heritage of Stone Tidal Weirs and raising awareness about their significance. The app's
interactive content and the collaboration with local communities were identified as key factors
in its success. The study also reveals that digital technologies can be effectively utilized to
promote and preserve cultural heritage and can foster collaboration and understanding between
local communities and visitors.
Therefore, In the future research and development phase, further data accumulation and indepth analysis of its effectiveness can be conducted. Subsequently, it can be extended to more
mature regions or countries for research and organization, such as Penghu County in Taiwan
and Japan. In the future educational promotion phase, it can continue to serve as a teaching tool
for communities, schools, and tourism, educating people about stone weirs and their
significance to the local area.

&#13;
Trade along the Maritime Silk Road has been going on for many centuries. Museum collections show a visible record of objects that were traded and historical sources provide important information of how this developed over time. Since the 1970’s many shipwrecks have been discovered that give an even better understanding of this intricate network. While more and more of these shipwreck are now being excavated in an archaeological manner, in the past most of them were salvaged for mainly commercial purposes. Many of these pieces have end up in museum collections. In this session several museums and institutions will give their approach on how they present this material, whether from an archaeological excavation, a commercial salvage or both. Which issues are addressed and what message do they convey to a wider public? The Princessehof will present about their current exhibition Sunken Treasures showing ceramic cargo from various shipwrecks. Featured will be a selection of 7 shipwrecks – from the 9th to 19th century – that show the long and rich history of the Maritime Silk Road. To highlight the vital role of underwater archaeology to preserve this history the museum cooperates with the Dutch Cultural Agency (RCE). The RCE will provide their view in this session on presenting this kind of material and the issues that come at play, including the controversy involved. The National Museum of Korea will present about the Sinan shipwreck. In 2016 the museum had a major exhibition on the Sinan shipwreck, celebrating the 40th anniversary of the excavation in 1976. It marked the beginning of underwater archaeology in Korea. The museum now still has a permanent display to tell the story of this remarkable find that contained crucial information on trade between China and Japan in the 14th century.&#13;

                <text>The National Museum of Prehistory (NMP) in Taiwan is the only national museum in eastern Taiwan and an important anthropology museum. The NMP has been working together with the National Museum of Nature and Science in Japan during three years to develop the program “Holistic Reenactment Project of the Voyage 30,000 Years Ago”. The aim of this project was to look into the origin of the Japanese people by testing whether it is possible to travel to the Japanese archipelago from Taiwan by using a raft. The project team inferred that ancient humans were most likely to use the Kuroshio Current to travel from Taiwan to the Okinawa Islands. In recent years, a succession of human skeletons from more than 20,000 years ago have been unearthed in Okinawa. As such, based on the distribution of animals, ocean Currents, Paleolithic human remains, DNA from unearthed skeletons, and social behaviors, it has been estimated that humans have occupied the islands of Okinawa for some 30,000 years. There is a strong possibility that these prehistoric settlers found their way to Okinawa by sea from Taiwan. Two bamboo rafts were built by a Taiwanese indigenous raft-maker to test this hypothesis. The knowledge and techniques of building bamboo rafts as practiced by Taiwan’s indigenous people are listed as intangible cultural heritage. The techniques and knowledge of making rafts are disappearing. We have tried to record how the rafts were made. In this study, we can see how museums can use intangible cultural heritage not only by collecting, protecting, researching and exhibiting this material, but also interpreting and representing it. In addition the NMP will present their results from the oceanic environmental education program developed over two years. </text>

Abstract
The Ryukyu Archipelago is located at the northwestern Pacific, between the islands of
Formosa and Kyushu of southern Japan. It consists of 199 islands of all dimensions and
the total range of its accurate distribution lengthen is approximately 1,200 km. Since the
first human beings settled down on the archipelago during the Pleistocene, they have
been living close by the sea there. The local populations have recognized maritime
resources as a main and important nutritious food since the prehistoric era, while the
Ryukyu kingdom used to be prosperous unprecedentedly in terms of seaborne oversea
trade among Japan, China, and Southeast Asia. In the Ryukyu archipelago, the
distributional survey of underwater cultural heritage has lately been conducted by the
Nansei Islands Underwater Cultural Heritage Study Group, the Okinawa Prefectural
Archaeological Center, the Asian Research Institute of Underwater Archaeology, and
Kagoshima University, in order to assess its numbers, typologies, actual conditions, and
so on. According to the research, 235 sites of underwater or maritime cultural heritage
have already been confirmed: 9 shipwrecks, 33 submerged ports, 15 places where boat
cargos are scattered on the seabed, 72 places where old boat cargos and other
remains are found along the coasts, 30 stone anchors and cargos on land, 28 quarries,
45 stone tidal weirs, and 3 salt works. In 2011, as a result of the survey, an underwater
cultural heritage presentation or guidance tour was carried out in Kume Island.
Presumably, this experimental trial will lead the public to having the sense to
acknowledge and protect underwater cultural heritage in the future.

Introduction
The Ryukyu Archipelago consists of 199 islands of various sizes ranging about 1,200
km between Kyushu Island, the southernmost island of the Japanese Archipelago, and
1

�Taiwan in the northwestern coastal Pacific. The first humans reached there in the late
Pleistocene and have long been living a life highly connected to the sea since then.
Marine resources had been their major food source in prehistory, and the islands have
prospered because of overseas exchanges using ships and the sea from the Gusuku
Period to the Sanzan Period (from the latter half of 11thcentury to 1429 AD). The tidal
zone was actively utilized for production activities until 1879, when the Ryukyu Kingdom
became an independent state. Recent research accumulation revealed the numbers
and types of underwater cultural heritage in this region by the Nansei Islands
Underwater Cultural Heritage Study Group, the Okinawa Prefectural Archaeological
Center, the Okinawa Prefectural Museum and Art Museum, the Asian Research
Institute of Underwater Archaeology, Kagoshima University, Tokai University and
Research Institute for Humanity and Nature, and so on. It is notable that such
researches include a whole series of different kinds
of methods, such as collection of oral histories,
interviews, archival researches, walking survey of the
coastal area and the seabed, and the like.
Based on the results of such researches, we have an
underwater site open day in Kumejima Island in
Okinawa for its experimental presentation on 11th
September 2011 and 28th September 2013. On
those days, we invited the willing public to visit and
see underwater sites under the supervision and

guidance by the experts. The Ohajima Underwater

Ryukyu

Site was selected for the subject of this experimental presentation as it was the most
suitable site on many reasons. We have collected the data regarding the interest of the
visitors, trying to justify the validity of the method we have adopted. The research aims
to lead to the protection and utilization of underwater cultural heritage.
Types and numbers of the sites holding Underwater Cultural Heritage
As shown in the Table 1, the area of sea around the Ryukyu Archipelago holds a wide
variety of underwater cultural heritage. 9 shipwreck sites, 15 seabed artifact scattering
sites (loads only, no hull found), 33 submerged ports, 72 coastal artifact scattering sites,
2

�76 production sites (28 quarries, 45 stone tidal weirs, an 3 salt pans), and 30 sites with
findings on land, such as stone and iron anchors are so far found and categorized.

Table 1.Aggregation of Underwater Cultural Heritage of the Ryukyu Island. (C. Katagiri)

Sites due to the Marine Accidents
Shipwreck sites (a): Often only the wreckage and pieces of ships found. They are
disturbed by natural phenomena like a typhoon or human disturbance like recovery after
having been stranded or sunk. Seabed artifact scattering sites (b): Generally formed by
loads thrown away from the ships, but sometimes caused by the wreck. Hard to
distinguish either unless wrecked hull pieces are found.
Sites formed by the Frequent Use of the Sea and Coastal Areas
Ports(c): Proving that the area had been used as a port, with anchors and artifacts of
various periods are found. Occasionally formed by the ship anchored there which
accidentally sunk? Coastal artifact scattering sites (d): Formed as a result of utilization
of the coastal area those who were living in the settlements there, such as cooking and
discarding which are distinguished from the ports.
Sites due to Production Activities
Found in the tidal zone. Quarries (e) are well-recognized and well-preserved while salt
pans(g) and stone tidal weirs(f) formed with the small pebbles piled are not preserved in
a good state. Such structures are meant to be constantly used and repaired, and will be
naturally destroyed once stopped being used. Many sites of this kind had been existed
3

�in the past, but the numbers dramatically decreased and hardly seen now. It is exigency
to record those sites.
Others
Artifacts that used to be on the seabed are often recovered on land and conserved as
cultural properties (h). Stone and iron anchors often apply to this case providing the clue
to the identification of the ships sailing in the area at that time.
Major characteristics of Underwater Cultural Heritage in the Region

�Underwater Cultural Heritage Related to Overseas Trade from the Sanzan Period
(the 14th Century AD) to the Ryukyu Kingdom Period (from 1429 AD to 1879)
From the latter half of the 14th century to the beginning of the 15th century, a crucial
turning point in the history of the region occurred regarding the transition of political
power when the sovereign was centered during the establishment of the Ryukyu
Kingdom. Ohajima Underwater site in Kumejima Island is one of the major sites during
this period (Fig. 2, Table 2, Site No.12, Miyagi et al., 2004; Tezuka et al., 2008; Katagiri,
2007). Large amount of celadon of the early Ming Dynasty China is found. Moreover, 2
Chinese stone anchors have been identified in Kumejima Island. Kumejima Island and
the surrounding sea area must have played a significant role in oversea trades during
the early Gusuku Period and Sanzan Period, proved by the density of underwater sites
and stone anchors dated back then.The Ryukyu Kingdom was in its heyday from the
15th century to the mid 16th century. The king resided in Shuri-jo Castle served as the
sovereign ruler and the centralized nation was formed then. Nagura-shitadaru site
(Underwater site) dated back to the mid to late 15th century is located in Ishigakijima
Island and large amount of Chinese celadon discovered from the site (Fig. 2, Table 2,
Site No. 22, Sakishima Culture Research Institute, 2009). Miyakojima Island holds
Kurimajima Underwater site dated back to the first half of the 16th century. Chinese
ceramics found from sites has been changing then, from the predominantly celadon
before to the gorgeous flowery blue and white porcelain (Fig. 2, Table2, Site No.19,
Katagiri, 2009).After the invasion of the Satsuma clan in 1609, Tokara-retto Islands
became a territory of Satsuma. An underwater sites indicating the maritime accident at
that time is identified in Tairajima Island of Tokara-retto Islands. Clusters of Chinese
porcelains of the Qing Dynasty dated to the 18th century found in the area, which would
have been formed by the ship sunken or the ship loads discarded (Fig. 2, Table 2, Site
No. 1, Kagoshima University, The Faculty of Law, Economic and Humanities et al.,
2010).
Sunken Shipwrecks Revealing Ikoku-sen (the Western Ships) during the Last
Years of the Ryukyu Kingdom
In the last years of Ryukyu Kingdom, many West European ships called Ikoku-sen has
constantly been around the sea area of the Ryukyu Archipelago.It is obvious that Asian
5

�intrusion and interference by the great powers of the West Europe came to influence so
far as the Ryukyu Kingdom. Many shipwrecks found in the area can provide us the
great deal of information on Western ships at that time. An English ship, Providence,
sunken in Yaebishi in Miyakojima Island in 1776 was discovered (Fig. 2, Table 2, Site
No.16, Katagiri, 2009). On top of the Providence, another English ship, Indian Oak,
owned by East India Company sunken in 1776 was found in Chatan-cho in Chatan Oki
(Fig. 2, Table2, Site No.9, Nakamura, 1994). In 1853, the same year with when Mathew
Calbraith Perry arrived at Uraga Port, an English ship sank off Yoshino Kaigan in
Miyakojima (Fig. 2, Table 2, Site No.20, Katagiri, 2009) and a Dutch Ship, Van Bosse off
Takada Kaigan in Taramason Village in 1857 (Fig. 2, Table 2, Site No.21, Katagiri, 2009).
In 1872, when the Ryukyu Kingdom was inclining on verge of collapse, an English ship,
Benares sank off Ginama in Kunigamison Village (Fig. 2, Table2, Site No.4, Katagiri,
2013), as well as a foreign ship of unknown nationality sank off Minamiukibarujima in
Uruma City (Fig. 2, Table 2, Site No.8, Katagiri, 2010). Wrecks and loads left by those
foreign ships still remain on the seabed of those areas.
Underwater Cultural Heritage Related to the Domestic Commodity Circulation
within the Ryukyu Kingdom.
In 1879, the Meiji Government abolished the Ryukyu Kingdom. The Kingdom became
extinct on the map and came to be called “Okinawa Prefecture”. The ships called
“Maran-sen” were playing significant role of carrying the supplies to many remote
islands in Okinawa at that time. Agonoura Underwater site located in Zamamijima Island
(Fig. 2, Table 2, Site No.11, Miyagi et al., 2004), Yaebisi Underwater site Cluster in
Miyakoshoto Islands (Fig. 2, Table2, Site No.2-3, Katagiri, 2009), Yarabu Underwater
Site in Ishigakijima Island (Fig. 2, Table2, Site No.23, Katagiri, 2010, Ono et al., 2013),
Sekiseishoko Underwater site Cluster in Yaeyamashoto Islands (Fig. 2, Table 2, Site
No.24-26, Katagiri, 2009, Ono et al.,2013) are so far identified underwater sites dated to
this period. A wide variety of Tsuboya-yaki pottery produced in Naha City in
Okinawajima Island are found in those sites, accompanied with some Chinese Qing
Dynasty Porcelain in some cases. Those sites and artifact scatterings were formed due
to the accident of the ships which were transporting pottery produced at Tsuboya in
Naha City of Okinawajima Island to the smaller islands around Okinawajima Island,
6

�such as Miyako and Yaeyama Shoto Islands, either by the hull being submerged or the
loads abandoned on their way. In case of Sekiseishoko Underwater site Cluster, Point
No. 3 (Fig. 2, Table 2, Site No. 26), the submerged hull is identified. Moreover, fourarmed anchors that had never seen on land in Okinawa are discovered at Yarabu
Underwater site (Fig. 2, Table 2, Site No. 23) in Ishigakijima Island, which provides us
significant information to reveal the appearance and characteristics of the ships at that
time (Katagiri, 2010; Ono et al., 2013).
Submerged Port Sites
Underwater sites showing evidence of having been the ports with frequent use are
Shirasegawakako (Fig. 2, Table 2, Site No.14,
Toma and Sakuda, 1999) and Majako (Fig. 2,
Table 2, Site No.15, Katagiri, 2007; 2010) in
Kumejima Island, Agonoura in Zamamijima
Island (Fig. 2, Table 2, Site No. 11, Katagiri,
2007),

tributary trades. There is a warehouse overseer

near the site and stone anchors are found from the nearby settlement. A wide variety of
artifacts dated back to from the medical to pre-modern and modern period are scattered
on the coast and seabed in this area, which support that the area had long been used
as a port (Fig. 2, Table 2, Site No.15). Combined investigations of such a site and
previously mentioned Nakanohama underwater site and Ohajima underwater site that
show the traces of maritime accidents will provide us with large amount of information to
evaluate the site. Agonoura of Zamamijima Island is also known as a port related to the
tributary trade.Many kinds of artifacts, such as the 15th century celadon, as well as the
pre-modern and modern pottery produced in Okinawa, have been discovered on the
seabed of the area (Fig. 2, Table 2, Site No.11).
Sesokojima Sea area had also long been used as port on the trade route, which
resulted in many artifacts findings especially on the east coast of Sesokojima Island. A
7

�stone anchor was found at Anchi-hama Beach, probing the existence of the ships
anchored there (Fig. 2, Table 2, Site No.7, Katagiri et al., 2005). This stone anchor is
relatively small, but mocking Chinese stone anchor having produced during the time of
the Ryukyu Kingdom. The small stone anchors of this kind have recently been found at
several places all over Okinawajima Island, which would be significant information
source to reveal the structure of Maran-sen ships. Several stone anchors of this kind
holding similar form were also found from the seabed off Sanko Port of Tokunoshima
Island (Fig. 2, Table 2, Site No.3, Kagoshima University, The Faculty of Law, Economic
and Humanities et al., 2010). The area was tactically significant sea area for the port,
and geographical as well as historical significance of the area are to be revealed.

and the like are so far identified (Fig.2, Table 2, Site No.31). Quarries are often well
preserved due to its structural characteristic, while stone tidal weirs and salt pans made
with small pebbles pile up are generally in disastrous preservation state. These types of
sites have to be constantly used and repaired. The site, once stopped being used,
would start to be reverted back to the original natural state and collapse due to the
natural force of waves and tide. There had been many salt pans and stone tidal weirs in
the past, which are hardly seen now. Recording of those sites is our urgent mission.

�Underwater Cultural Heritage Raised on Land
There are some artifacts and parts of ship structure, which had been found on the
seabed, raised on land, and then preserved and reverted to the cultural properties.
Their information and use would be enhanced and its value increased by being
connected with underwater cultural heritage in the area that still remains to be
underwater. A stone anchor reused for the well of a Yamada Gusuku (Castle) in
Onnason Village (Fig. 2, Table 2, Site No.34, Katagiri, 2007), iron anchors in
Taramajima Island (Fig. 2, Table 2, Site No.35, Katagiri, 2009), stone materials found in
Yoshino Settlement in Miyakojima Island (Fig. 2, Table 2, Site No.36, Katagiri, 2009),
iron products of Miyako-Ikemajima Island and the like are so far recognized of this kind
(Fig. 2, Table 2, Site No.37). They provide us the clue to figure out the ships sailing in
this sea area.
Experimental Site Open Day
After the 10 years of distributional survey in sea area of the Ryukyu Archipelago, as a
result, we now have a rough idea about the types and quantity of underwater cultural
heritage in the area. The next step forward is to search for a method for protection and
utilization of such cultural heritage bore in the beautiful sea in this region with high
degree of transparency formed by coral leaf. For this purpose, we have experimentally
undertaken a public site open day for underwater cultural heritage around Kumejima
Island in Kumejimacho (Katagiri et al., 2012).
Fig. 3 shows Landscape of Ohajima underwater site and sea area that held a tour.The
major attraction of the day was Ohajima Underwater Site with dense distribution of
Chinese pottery dated back to between the latter half of the 14th century and beginning
of the 15th century. For the better understanding of the nature and characteristics of
underwater cultural heritage, we had delivered a preliminary lecture for 30 minutes
before the site visit, as well as observation tour of the artifacts already raised on land,
such as pottery pieces collected from the seabed at Ohajima and a stone anchor found
at UeGusuku (castle) for 30 minutes. Furthermore, we organized a tour visiting related
cultural heritage sites on land, such as Tenkogu Site, Kuramoto-ato Site, Majako Port
Site, quarries, and the like, for an hour, which aimed at explaining why the underwater
site had been formed on seabed of Ohajima. We prepared 2 ways to visit for the actual
10

�visit of Ohajima Underwater site on seabed, both of which last for about an hour. We
organized 2 groups of people with 20 people each, one for visiting the site by snorkeling
and the other by a glass-bottom boat for those who are not willing to go into the water.
Fig. 4 shows the tour scene of snorkel in Ohajima Underwater Site. This attempt was
able to establish a model case for the site open day for the public visiting underwater
cultural heritage, which could be followed by the other sites in the Ryukyu Archipelago
although we still have to scrutinize this case to evaluate how far the case can be applied
to the other cases as well as to the wider public.
Conclusion
History and culture of the Ryukyu Archipelago have long been together with the sea.
Due to its few resources and small areas, it is often claimed that island areas provide
harsh environment for the life and survival of human-being. Nevertheless, there is a
distinctive maritime culture which have overcome and formed till now. The distinctive
characteristics and history of such culture has not yet been fully revealed and evaluated
even now. It needs further investigations. We believe that study of underwater cultural
heritage would be essential field of research for the future of this area around the
Ryukyu Archipelago. The researches so far done helped us to identify a wide variety of
underwater cultural heritage ranging from the medial to the pre-modern and modern
period. It is also found out that most sites tend to be related to the trade, port and
production activity. Now, after the distributional survey, further intensive investigation
on a particular area needs to be carried out. Even though we are still facing many
problems for conservation and utilization of the site, utilization of underwater cultural
heritage in the Ryukyu Archipelago has a bright future, we believe. Many people from all
over the world visit Okinawa to enjoy the observation of the seabed of the area by
marine sports and glass-bottom boats. As it has been undertaken in Kumejima Island,
the concept of establishing Seabed Site Museums is ideal way of utilization for such
environment with beautiful sea in the Ryukyu Archipelago. We further intend to promote
this attempt to the other sea area.

                  <text>East Asia is rich in maritime and underwater cultural heritage. Not only conventional shipwrecks or submerged archaeological sites but also stone tidal weirs or prehistoric shell mounds along coastal zones have extensively been identified by many researchers. Most countries have just started in directing the heritage management in order to preserve them well, but the process of trial and error is still going on. In addition, no Asian nation, except for Cambodia and Iran, has ratified the UNESCOâ€™s 2001 convention yet, partly because of territorial disputes over the sea among several East and Southeast Asian governments. It would be foolish to rule out political considerations when we study maritime or underwater archaeology in Asia.&#13;
This session showcases papers about the history and current trends of maritime or underwater archaeology around East Asia. It may includes papers focusing upon historical backgrounds or wakeup calls of underwater cultural studies, ongoing excavations, grass roots movements, legislation efforts, contemporary political matters, and so forth. In 1890 an Ottoman frigate sunk within Japanese territorial waters; her wreck has lately been salvaged by foreign hunters who disregard its domestic law for the protection of cultural properties, while Japanese academic institutions or underwater archaeological organizations have been kept away from the excavation activities. Papers on points raised from such case studies will also be welcomed. </text>

                <text>The Ryukyu Archipelago is located at the northwestern Pacific, between the islands of Formosa and Kyushu of southern Japan. It consists of 199 islands of all dimensions and the total range of its accurate distribution lengthen is approximately 1,200 km. Since the first human beings settled down on the archipelago during the Pleistocene, they have been living close by the sea there.  The local populations have recognized maritime resources as a main and important nutritious food since the prehistoric era, while the Ryukyu kingdom used to be prosperous unprecedentedly in terms of seaborne oversea trade among Japan, China, and Southeast Asia.  In the Ryukyu archipelago, the distributional survey of underwater cultural heritage has lately been conducted by the Nansei Islands Underwater Cultural Heritage Study Group, the Okinawa Prefectural Archaeological Center, the Asian Research Institute of Underwater Archaeology, and Kagoshima University, in order to assess its numbers, typologies, actual conditions, and so on.  According to the research, 235 sites of underwater or maritime cultural heritage have already been confirmed: 9 shipwrecks, 33 submerged ports, 15 places where boat cargos are scattered on the seabed, 72 places where old boat cargos and other remains are found along the coasts, 30 stone anchors and cargos on land, 28 quarries, 45 stone tidal weirs, and 3 salt works. In 2011, as a result of the survey, an underwater cultural heritage presentation or guidance tour was carried out in Kume Island.  Presumably, this experimental trial will lead the public to having the sense to acknowledge and protect underwater cultural heritage in the future.</text>

Abstract
Extensive distributional survey of the underwater cultural heritage
revealed the disposition of 230 underwater cultural heritage sites in the
Ryukyu Archipelago, and 23 sites out of 230 are identified as the wreck
sites. Dates of these wrecks vary from the 12th to 20th centuries;
nevertheless, all the Western shipwrecks found at six sites are dated to
within about 100 years between the latter half of the 18th century to the
19th century. This presentation is about the Western shipwrecks left in the
sea area of the Ryukyu Kingdom. From the late 18th century, the ships
from the Western powers stared to appear frequently. Historical
documents describes that those ships had not intended to come to the
kingdom, but were wrecked due to maritime accidents. Such incidents
brought opportunities for local population to come into contact with the
Westerners though rescuing the wrecks and their crews. Historical
documents and local lore, confirmed by the material evidence retrieved
from the seabed, show that those contacts in some cases developed to
the cultural interaction between local governments, or even nation-tonation. Moreover, the stories of the accidents and rescue efforts by the
local have long been handed down from generation to generation as
moving tales. In fact, there are some cases that those tales were
materialised, for instance in forms of a reconstructed Western ship

�facilitated as play equipment in a local park near the wreck site, as well as
an amusement park themed under the country of the wreck’s nationality.
This research aims to present how the archaeological evidence confirm
historical records related to the Western shipwrecks though the result of
investigation of underwater cultural heritage, as well as to analyse how
those initial contacts with the Westerners though the wreck accidents
developed into the cultural interaction which can be influential even now.

Introduction
The Ryukyu Archipelago consists of 199 islands, in a stunning vast sea
area over 1200km between Kyushu Island, located at southern end of
the Japanese Archipelago, and Taiwan. The largest island among the
Ryukyu Archipelago is Okinawa Island, where the present prefectural
government is seated. It is located almost at the centre of the
archipelago (Fig. 1). Being different from the Japanese Archipelago, the
islands of Ryukyu are under subtropical climate, warm throughout the
year. Surrounded by the amazingly beautiful ocean and coral reefs, the
area is also known for scuba diving and other marine sports.

�Fig. 1: Ryukyu Archipelago.

Various kinds of underwater cultural heritage have been discovered so far
and the authors have been continuously undertaking investigations and
researches (Katagiri, et al., 2014a and Ono et al., 2016). Results of our
distributional survey on underwater cultural heritage and its experimental
presentation in the Ryukyu Archipelago were presented at APCONF,
Hawaii in 2014 (Katagiri et al., 2014b). Researches on the wreck sites
and sea routes of the ships in the Ryukyu Archipelago were presented at
IKUWA, Australia in 2016 (Katagiri et al., 2016). This presentation focuses
on the Western shipwreck sites among the shipwreck sites discovered in
the Ryukyu Archipelago.

�Historical Background
There once was an independent kingdom in the Ryukyu Archipelago,
called the Ryukyu Kingdom from 1429AD to 1879AD. There was the
capital palace, Shurijo, in Okinawa Island, the largest among the
archipelago. The palace was the hub of the kingdom where the Ryukyu
King who rules the islands lived. The Ryukyu Kingdom was a maritime
state having thrived during the medieval, the 15th centuries, owing much
to the special relationship with the Ming Dynasty China regarding the
trades.

It greatly flourished on transit trade connecting Japan, Korea,

China and Southeast Asia. The international Naha Port was the centre of
the international trades (Fig. 1). In the following early modern times from
the 17th to 19th centuries, while subordinating to both Qing Dynasty China
and Japan, the kingdom prospered many original aspects in their complex
culture. On one hand, the kingdom had established domestic trade
networks among the islands. On the other hand, the Tokugawa Shogunate
prohibited international trades with other countries than China under the
policy of national isolation (‘Sakoku’) and the kingdom was becoming
isolated from international community. Nevertheless, since the latter half
of the 18th century, the ships of the Western great powers started to
appear in the sea areas of the kingdom. People in the kingdom started to
have contacts with Western ships and the Westerners through rescue of
the Western ships stranded in the neighbouring sea areas. In a historical
drawing on the folding screen, ‘Suirinahakozubyobu’ (owned by Okinawa
Prefectural Museum and Art Museum) painted in the 19th century,
depicting the prosperity of Naha Port, Western ships are also depicted
(Fig. 2). Contrary to the national isolation foreign policy, it is proven that
the Western ships frequently appeared in the sea area of the Ryukyu
Archipelago and was regularly in contact with the Ryukyu Kingdom.

�Fig. 2: Western Ships at Naha Port in the 19th Century
Nationalities and Proportions of the Western Ships Discovered in the
Ryukyu Archipelago
Figure 3 shows the percentage of the shipwreck sites to the entire
underwater cultural heritage discovered in the Ryukyu Archipelago,
percentage of the Western shipwreck site to the entire shipwreck sites,
and percentage of their nationalities.

Underwater cultural heritage

discovered in the Ryukyu Archipelago includes shipwreck sites, ports,
production sites (like quarries, stone tidal weirs and salt pans) and
submerged sites due to environmental change. The shipwreck sites total
23 sites, which accounts for ten percent of the whole.

�Fig. 3: Percentage of the Shipwreck Sites in the Ryukyu Archipelago.
The shipwreck sites according to its nature can be categorized into three
groups; those related to the trading, those not related to the trade, and the
World War II related sites. The first group of the shipwreck sites relate to
trading; this includes those of Chinese trade ships and domestic trade
ships. Among the sites of Chinese trade ships, seven sites are dated to
the medieval and one to the early modern period, both in total account for
35 percent of the whole shipwreck sites. All eight domestic trade ships
sites are dated to the early modern period, which accounts for 35 percent
of the whole showing the same proportion as Chinese trade ships.
Chinese and domestic trades ships together count 16 sites, which
accounts for 70 percent of the entire shipwreck sites in the Ryukyu
Archipelago.
In contrast, the Western ships appeared in the sea area of the Ryukyu

�Kingdom not for trades, but for other purposes. According to the historical
documents, they were destined to travel toe different places, but were
stranded and sunk in Ryukyu due to typhoons or the like. Six sites with
Western shipwrecks were identified so far, which accounts for 26 percent.
The date of all six sites are concentrated within c. 100 years between the
latter half of the 18th century and the latter half of the 19th century, which
does not conflict with the historical background of the kingdom.
Nationalities of the most Western shipwrecks were identified through the
historical records. Four sites out of six are British ships, one Dutch, and
one unidentified. Even though the evidence if limited, the British
overwhelm the others.
Location of the Western Shipwreck Sites
Figure 4 shows location of the Western shipwreck sites found in the
Ryukyu Archipelago (No. 1 to 6), as well as the location of the iron stock
anchors of the Western ships (A to C) discovered both underwater and on
land. Figure 5 is the respective pictures.

�Three Western shipwreck sites are identified in Okinawa Island (No. 1 to
3) where the capital Shurijo used to be located, two in Miyako Island (No.
4 and 5) and one in Tarama Island (No. 6). In Yaeyama Islands located at
the southern border of the Ryukyu Kingdom, no site with Western
shipwreck has been discovered so far. Moreover, regarding the iron stock
anchors of the Western ships, two are found on land, one in Okinawa
Island (A) and one in Tarama Island (B), as well as one underwater in the
sea area around Yonaguni Island (C).
The Outline of the Respective Western Shipwreck Sites.
Ginama Underwater Site (No. 1; A):
The site is located off the coast of Kunigami Village in Okinawa Island, on
the seabed of about seven meter deep. Nansei Islands Underwater
Cultural Heritage Research Group discovered the site in 2002 (Miyagi et
al., 2004). Fragments of the hull, such as copper nails, European
ceramics, wine bottles and Chinese pottery pieces were found on the
seabed. Historical documents revealed that the ship is a British ship called
the Benares, departed from Hong Kong destined to San Francisco
(Watanabe and Nii, 2013). Building stones of granite and an iron stock
anchor reportedly retrieved from the British ships were left in the
neighboring areas on land.
Minamiukibarujima Underwater Site (No. 2):
The site is located off the Coast of Minamiukibaru Island in Uruma City,
Okinawa Island on the seabed of about 17 metre deep. It has been known
for long by the local fishermen. Okinawa Prefectural Archaeological

�Centre identified it as the Western shipwreck sites (Katagiri, 2009).
Fragments of the hull, ballast, European ceramics, glass products, bullets
and Chinese pottery pieces were found on the seabed. Historical
documents descrees that a Western ship was stranded and sunk in the
sea off the island in 1876, but its nationality is unidentified (Heshikiya
Azashi Henshu Iinkai, 2009).
Indian Oak Wreck Site (No. 3):
The site is located off the coast of Chatancho in Okinawa Island and found
at a depth of about three metres. The Board of Education in Chatancho
undertook the underwater investigation in 1984 and retrieved fragments
of the hull like copper nails and pieces of copper sheathing, ballast stones,
European ceramics, glass products, Chinese pottery pieces and the like
were found. Historical documents revealed that the ship was the Indian
Oak who had been fighting in the Opium War in 1840. The ship was drifted
to the sea area while she had been transporting supplies (Nakamura,
1994).
Yabiji Underwater Site No.3 (No. 4):
The site is found at a depth of about 13 metres around the coral reef called
Yabiji located in the sea area north of Miyako Island. The site was
identified by the survey of Okinawa Prefectural Archaeological Center
(Katagiri, 2009). Metal parts of the hull, European ceramics, glass
products and iron ingot like products were discovered from the seabed.
Historical documents indicate that the ship could be assumed as HMS
Providence stranded in 1797 during her exploratory voyage in the North
Pacific (Nagamine, 1997).
Yoshinokaiganoki Underwater Site (No. 5):

�The site is located off Yoshino Coast of Miyako Island, found on the
seabed

at

about

five

metres

deep. The

Okinawa

Prefectural

Archaeological Centre discovered the site in 2008 (Katagiri, 2009). Many
pieces of granite stone blocks processed into cuboid shape are scattered
on the seabed. Fragments of the hull, for instance copper sheathing, as
well as Thai pottery pieces were also found (Arakaki, 2017). Historical
documents indicates that the ship could have been a British ship stranded
and sunk in 1853 on the way from Guangzhou in China to San Francisco.
The document shows that only 6 crew out of 30 and 24 Coolies out of 243
survived, and thus 243 people died of this accident (Taira, 2001).
Takadakaigainoki Underwater Site (No. 6):
The site is located off Takada Coast of Tarama Island. Many pieces of
pottery are scattered on the seabed at about 25 metre deep. The place
was reportedly known among the islanders as the site where a Dutch ship
had been stranded and sunk. The Okinawa Prefectural Archaeological
Center undertook the first underwater survey in 2008 and identified that
the site covers large area (Katagiri, 2010). Fragments of the hull, including
copper nails, metal products, and Chinese ceramic pieces were found on
the seabed (Arakaki, 2017). Historical documents reveal that the ship was
a Dutch ship called Van Bosse, stranded and sunk in 1857 on the way
from Shanghai to Singapore (Kaneda, 2001). There is an iron stock
anchor reported to be retrieved from this ship (B) left on land, as well as a
ceramic piece incised as ‘AMSTERDAM’ and Chinese pottery assumed
to be the cargo (Miyagi et al., 2004).
Education

and

Kyushu

National

The Tarama Village Board of
Museum

recently

undertook

comprehensive investigation and the use of metal detector revealed that
the fragments of the hull were still buried in the sandy seabed (Sasaki,
2017).

�Iron Stock Anchor off the Coast of Irizaki, Yonaguni Island (C):
It is not identified as a Western shipwreck site, but an iron stock anchor of
Western design was discovered off the coast of Irizaki at Yonaguni Island,
on the seabed about 26 metre deep (Katagiri and Yamamoto, 2014). Its
nationality and other details are unknown.
Influence on the Contemporary Society
It is generally said that Captain Basil Hall was the first Westerner visited
Ryukyu and introduced to Europe geography, customs, political and
economic states and the like of Ryukyu based on his careful observation.
On his way going back to Britain, he interviewed to Napoleon Buonaparte
at St. Helena Island. It is a famous story that he told Buonaparte that
people of Loo Choo (Ryukyu) had no arms, used no money and knew
nothing of Europe and His Majesty Napoleon Buonaparte (Hall, 1851 and
1986). Interestingly, Hall was convinced that the people in Ryukyu did not
use money as they did not receive payment of any kind from Hall’s
company for gratitude to all good things sent on board (Hall, 1851). This
description coincides with descriptions often seen in the historic document
of the western sides that shows surprise on Ryukyu people’s hospitality
with no expectation in return. Since then, Western ships coming to Ryukyu
dramatically increased. The phenomenon was not only reported by oral
histories and historical records, but also proved by the material evidence
at many underwater wreck sites of the Western ships by their discoveries
around the Ryukyu Archipelago.
The influence of those Western shipwrecks is seen even now. There is a
park near the wreck site of Indian Oak (No.3), a British ship joined the

�Opium War in 1840, and the play equipment set there in the design of the
reconstructed Indian Oak (Fig. 6). Moreover, there is a theme park caller
‘German Village’ in Miyako Island near the reportedly wreck site of a
German ship, the R. J. Robertson (even though the site not mentioned
above in this presentation as was not identified in the sea). The theme
park is run by the municipality of Miyako City and people of the island are
proud of the history of the rescue. Triggered by those rescue stories, the
UK Prime Minister Tony Blair and the German Prime Minister Gerhard
Schröder visited Chatancho and Miyako City respectively to strength
cultural exchanges when a summit conference had been held at Okinawa
in 2000. In case of HMS Providence, although no park nor theme park,
the local volunteers organised a group to commemorate HMS Providence
(HMS Providence wo Kataru Kai). The group promotes cultural exchanges
with England as the country of her origin and Hokkaido where she called
at.

Shipwreck
Sites.

�Curiously, it is often said in gossip that many beautiful women with fair
skin were born in the villages near the sites where the Western ships had
stranded and the Westerner crews were rescued. Those incidents prove
that history of shipwrecks and their rescue stories dated back to more than
a hundred years ago still has great influences on current society as
bridging cultural exchanges between the Western world and Okinawa.
Shipwreck sites in Okinawa are the valuable heritage as the material
evidence of those incidents.

In the future, further investigation and

research on the Western shipwreck sites could promote cultural
exchanges of the related countries and local places through exchanging
and sharing information. The result of such activities could even be a
trigger to develop large-scale international cultural interactions which
could be a leading model-case project representing current globalised
society.

                  <text>East Asia is extremely rich in underwater cultural heritage, such as conventional shipwrecks under the sea, submerged settlement sites on the bottoms of inland lakes and rivers, or prehistoric shell mounds along coastal zones.  For instance, the medieval or post-medieval aged wrecks and their cargos have recently been discovered one after another in the waters, or the underwater cultural heritage or seascape of stone tidal weir is a common cultural trait to the Ryukyu archipelago, western Japan, southern Korea, mainland China, and Formosa, which surround the East China Sea or a northern part of the Asian Mediterranean. No East Asian nation has ratified the UNESCO 2001 Convention, partly because it does not exactly correspond with oriental philosophy, it does not properly resolve the controversial issues upon sovereign immunity of warship wrecks, and so forth.  Occasionally, the principle of preservation in situ in the convention has not been the first choice as Asian waters have poor water clarity generally.  &#13;
&#13;
Nevertheless, each country has already moved forward with its own underwater archaeological policies and projects both on governmental and grassroots levels.  Some activities are in close cooperation with foreign institutions or universities.  In East Asia, document-based historical study or terrestrial archaeology has a long tradition, which has had a noteworthy impact upon underwater archaeology and its methodology.  Even in this region as well as in other Pacific areas, contrariwise, the technological advancement in underwater survey has remarkably been made recently; using remote-sensing with satellites, robotics for ROVs or AUVs, or 3D photogrammetry by computer software mitigates or cancels the limitations regarding accessibility and working time caused by underwater environment.  The tie between such modern technologies and archaeology has minted new applications and perspectives of underwater cultural heritage study.  The multi-disciplinary or holistic approaches are increasingly more and more necessary among Asian researchers.  &#13;

                <text>Extensive distributional survey of the underwater cultural heritage revealed the disposition of 230 underwater cultural heritage sites in the Ryukyu Archipelago, and 23 sites out of 230 are identified as the wreck sites. Dates of these wrecks vary from the 12th to 20th centuries; nevertheless, all the Western shipwrecks found at six sites are dated to within about 100 years between the latter half of the 18th century to the 19th century. This presentation is about the Western shipwrecks left in the sea area of the Ryukyu Kingdom. From the late 18th century, the ships from the Western powers stared to appear frequently. Historical documents describes that those ships had not intended to come to the kingdom, but were wrecked due to maritime accidents. Such incidents brought opportunities for local population to come into contact with the Westerners though rescuing the wrecks and their crews.  Historical documents and local lore, confirmed by the material evidence retrieved from the seabed, show that those contacts in some cases developed to the cultural interaction between local governments, or even nation-tonation. Moreover, the stories of the accidents and rescue efforts by the local have long been handed down from generation to generation as moving tales. In fact, there are some cases that those tales were materialised, for instance in forms of a reconstructed Western ship &#13;
facilitated as play equipment in a local park near the wreck site, as well as an amusement park themed under the country of the wreckâ€™s nationality.  This research aims to present how the archaeological evidence confirm historical records related to the Western shipwrecks though the result of investigation of underwater cultural heritage, as well as to analyse how those initial contacts with the Westerners though the wreck accidents developed into the cultural interaction which can be influential even now. </text>
