Ha Long Bay

Ha Long Bay, in the Gulf of Tonkin, includes some 1,600 islands and islets, forming a spectacular seascape of limestone pillars. Because of their precipitous nature, most of the islands are uninhabited and unaffected by a human presence. The site’s outstanding scenic beauty is complemented by its great biological interest.

Outstanding Universal Value

Brief synthesis

Ha Long Bay, located in the Gulf of Tonkin, within Quang Ninh Province, in the northeast of Vietnam, is165 km from the capital of Ha Noi. Covering an area of 43,400 ha and including over 1600 islands and islets, most of which are uninhabitated and unaffected by humans, it forms a spectacular seascape of limestone pillars and is an ideal model of a mature Karst landscape developed during a warm and wet tropical climate. The property’s exceptional scenic beauty is complemented by its great biological interest.

The outstanding value of the property is centered around the drowned limestone karst landforms, displaying spectacular pillars with a variety of coastal erosional features such as arches and caves which form a majestic natural scenery. The repeated regression and transgression of the sea on the limestone karst over geological time has produced a mature landscape of clusters of conical peaks and isolated towers which were modified by sea invasion, adding an extra elemant to the process of lateral undercutting of the limstone towers and islands.

Criterion (vii): Comprised of a multitude of limestone islands and islets rising from the sea, in a variety of sizes and shapes and presenting picturesque, unspoiled nature, Ha Long Bay is a spectacular seascape sculpted by nature. The property retains a high level of naturalness, and despite its long history of human use,  is not seriously degraded. Outstanding features of the property include the magnificent towering limestone pillars and associated notches, arches and caves, which are exceptionally well-developed and among the best presented of their type in the world.

Criterion (viii):  As the most extensive and best known example of marine-invaded tower karst in the world Ha Long Bay is one of the world’s most important areas of Fengcong (clusters of conical peaks) and Fenglin (isolated tower features) karst. Abundant lakes, occupying drowned dolines, are one of the distinctive features of the Fencong karst, with some appearing to be tidal. Possessing a tremendous diversity of caves and other landforms derived from the unusual geomorphological process of marine invaded tower karst the caves are of three main types: remnants of phreatic caves; old karstic foot caves and marine notch caves. The property also displays the full range of karst formation processes on a very large scale and over a very long period of geological time, possessing the most complete and extensive exzample of its type in the world and providing a unique and extensive reservoir of data for the future understanding of geoclimatic history and the nature of karst processes in a complex environment.

The Phong Nha-Ke Bang National Park, inscribed on the World Heritage List in 2003, covered 85,754 hectares. With this extension, the site covers a total surface area of 126,236 hectares (a 46 % increase) and shares a boundary with the Hin Namno Nature Reserve in the Peoples Democratic Republic of Laos. The Park’s landscape is formed by limestone plateaux and tropical forests. It features great geological diversity and offers spectacular phenomena, including a large number of caves and underground rivers. The site harbours a high level of biodiversity and many endemic species. The extension ensures a more coherent ecosystem while providing additional protection to the catchment areas that are of vital importance for the integrity of limestone landscapes.

 

Outstanding Universal Value

Brief synthesis

Phong Nha-Ke Bang National Park is located in the middle of the Annamite Mountain Range in Quang Binh province, Viet Nam, and shares its boundary with the Hin Namno Nature Reserve in the Lao PDR to the west. The property comprises an area of 123,326 ha and contains terrestrial and aquatic habitats, primary and secondary forest, sites of natural regeneration, tropical dense forests and savanna and is rich in large, often spectacular and scientifically significant caves.

The property contains and protects over 104 km of caves and underground rivers making it one of the most outstanding limestone karst ecosystems in the world. The karst formation has evolved since the Palaeozoic period (some 400 million years ago) and as such is the oldest major karst area in Asia. Subject to massive tectonic changes, the karst landscape is extremely complex, comprising a series of rock types that are interbedded in complex ways and with many geomorphic features. The karst landscape is not only complex but also ancient, with high geodiversity and geomorphic features of considerable significance.

The karst formation process has led to the creation of not only underground rivers but also a variety of cave types including: dry caves, terraced caves, suspended caves, dendritic caves and intersecting caves. With a length of over 44.5 km the Phong Nha cave is the most famous of the system with tour boats able to penetrate inside to a distance of 1,500 m. The Son Doong Cave, first explored in 2009, is believed to contain the world’s largest cave passage in terms of diameter and continuity.

A large number of faunal and floral species occur within the property with over 800 vertebrate species recorded comprising 154 mammals, 117 reptiles, 58 amphibians, 314 birds and 170 fish. The property clearly has impressive levels of biodiversity within its intact forest cover, notwithstanding some gaps in knowledge of the population status of some species. .

Criterion (viii): Phong Nha-Ke Bang National Park is part of a larger dissected plateau, which encompasses the Phong Nha, Ke Bang and Hin Namno karsts. The limestone is not continuous and demonstrates complex interbedding with shales and sandstones. This has led to a particularly distinctive topography. The caves demonstrate a discrete sequence of events, leaving behind different levels of ancient abandoned passages; evidence of major changes in the routes of underground rivers; changes in the solutional regime; deposition and later re-solution of giant speleothems and unusual features such as sub-aerial stromatolites. On the surface, there is a striking series of natural landscapes, ranging from deeply dissected ranges and plateaux to an immense polje. There is evidence of at least one period of hydrothermal activity in the evolution of this ancient mature karst system. The Son Doong Cave, first explored in 2009, could contain the world’s largest cave passage in terms of diameter and continuity. The plateau is one of the finest and most distinctive examples of a complex karst landform in Southeast Asia and the property is of great importance for enhancing our understanding of the geologic, geomorphic and geo-chronological history of the region.

Criterion (ix): Phong Nha-Ke Bang National Park consists of a complex limestone landscape, which includes very large caves and underground rivers. The property includes karst formations which are some of the oldest and largest in Asia, and it has geological, climatic, hydrographic and ecological conditions which are distinct from other limestone karst landscapes. Its cave ecosystems and habitats are unique with high levels of endemism and adaptations displayed by cave-dependent species. The property constitutes one of the largest remaining areas of relatively intact moist forest on karst in Indochina, with a forest cover estimated to reach 94%, of which 84% is thought to be primary forest. Furthermore, the property protects globally significant ecosystems within the Northern Annamites Rainforests and Annamite Range Moist Forests priority ecoregions.

Criterion (x): A high level of biodiversity is found within the property, with over 2,700 species of vascular plants and over 800 vertebrate species. Several globally threatened species are also present: 133 plant species and 104 vertebrate species have been reported, including several large mammals such as the endangered Large-antlered Muntjac, Clouded Leopard, and the critically endangered Saola. The level of endemism is high, especially in the cave systems. Furthermore, it is estimated that over 400 plant species endemic to Viet Nam are found within the property, as well as 38 animal species endemic to the Annamite range. Several new species to science have recently been found, including cave scorpions, fish, lizards, snakes and turtles, and more species are likely to be discovered. Importantly, four threatened primate taxa endemic to the Annamites are found within the property: the Hatinh Langur (specialised in karst forest and endemic to Viet Nam and the People’s Democratic Republic of Lao), the black form of the Hatinh Langur, sometimes considered as a separate species, the Red-shanked Douc Langur, and the largest remaining population of White-cheeked Gibbon.

Trang An Landscape Complex

Trang An Landscape Complex

Situated near the southern margin of the Red River Delta, the Trang An Landscape Complex is a spectacular landscape of limestone karst peaks permeated with valleys, many of them partly submerged and surrounded by steep, almost vertical cliffs. Exploration of caves at different altitudes has revealed archaeological traces of human activity over a continuous period of more than 30,000 years. They illustrate the occupation of these mountains by seasonal hunter-gatherers and how they adapted to major climatic and environmental changes, especially the repeated inundation of the landscape by the sea after the last ice age. The story of human occupation continues through the Neolithic and Bronze Ages to the historical era. Hoa Lu, the ancient capital of Viet Nam, was strategically established here in the 10th and 11th centuries AD. The property also contains temples, pagodas, paddy-fields and small villages.

 

Outstanding Universal Value

Brief synthesis

Located within Ninh Binh Province of North Vietnam near the southern margin of the Red River Delta, the Trang An Landscape Complex (Trang An) is a mixed cultural and natural property contained mostly within three protected areas; the Hoa Lu Ancient Capital, the Trang An-Tam Coc-Bich Dong Scenic Landscape, and the Hoa Lu Special-Use Forest. The property covers 6,226 hectares within the Trang An limestone massif, and is surrounded by a buffer zone of 6,026 hectares, mostly rural land with rice paddy fields. There are about 14,000 residents, the majority of whom are families involved in subsistence agriculture, but much of the property is uninhabited and in a natural state.

Trang An is of global significance as an outstanding humid tropical tower-karst landscape in the final stages of geomorphic evolution. It is composed of a variety of classical karst cones and towers and a network of enclosed depressions connected by an intricate system of subterranean waterways, some of which are navigable by small boats. The area is unique in having been invaded by the sea several times in the recent geological past but is now emergent on land. The blend of towering mountains draped in natural rain forest, with large internal basins and narrow cave passages containing quietly flowing waters, creates an extraordinarily beautiful and tranquil landscape.

Archaeological deposits in caves reveal a regionally significant, continuous sequence of human occupation and utilization spanning more than 30,000 years. There is convincing evidence showing how early human groups adapted to changing landscapes in the massif, including some of the most extreme climatic and environmental changes in the planet’s recent history.

Criterion (v): Trang An is an outstanding locale within Southeast Asia, for demonstrating the way early humans interacted with the natural landscape and adapted to major changes in climatic, geographical and environmental conditions over a period of more than 30,000 years. The long cultural history is closely associated with geological evolution of the Trang An limestone massif in late Pleistocene and early Holocene times, when the inhabitants endured some of the most turbulent climatic and environmental changes in Earth history, including repeated submergence of the landscape due to oscillating sea levels. Within the one compact landscape there are many sites covering multiple periods and functions, comprising early human settlement systems.

Criterion (vii): The exceptionally beautiful tower-karst landscape of Trang An is dominated by a spectacular array of forest-mantled limestone rock towers up to 200m high, which are linked in places by sharp ridges enclosing deep depressions filled by waterways that are inter-connected by a myriad of subterranean cave passages.  These features all contribute to a multi-sensory visitor experience that is heightened by contrasting and ever-changing colours – the deep green tropical rainforests, grey limestone rocks and cliffs, blue-green waters and the brilliant blue of the sky, and areas of human use including the green and yellow rice paddies. Visitors, conveyed in traditional sampans rowed by local guides, experience an intimate connection with the natural environment and a relaxing sense of serenity and security. The dramatic mountains, secretive caves and sacred places in Trang An have inspired people through countless generations.

Criterion (viii): Trang An is a superb geological property that displays, in a globally exceptional way, the final stages of tower-karst landscape evolution in a humid tropical environment. Deep dissection of an uplifted limestone massif over a period of five million years has produced a series of classical karst landforms, including cones, towers, enclosed depressions (cockpits), interior-draining valleys (poljes), foot- caves and subterranean cave passages decorated with speleothems. The presence of transitional forms between ‘fengcong’ karst with ridges connecting towers, and ‘fenglin’ karst where towers stand isolated on alluvial plains, is an extremely significant feature of the property. Trang An is an unusual autogenic karst system, being rain-fed only and hydrologically isolated from rivers in the surrounding terrain.  Former inundation by the sea transformed the massif into an archipelago for some periods, though it is fully emergent on land today. Fluctuations of sea level are evidenced by an altitudinal series of erosion notches in cliffs, with associated caves, wave-cut platforms, beach deposits and marine shell layers.

Criteria: (ii)(iv)

Property : 155.5 ha

Buffer zone: 5,078.5 ha

Citadel of the Ho Dynasty

The 14th -century Ho Dynasty citadel, built according to the feng shui principles, testifies to the flowering of neo-Confucianism in late 14th century Viet Nam and its spread to other parts of east Asia. According to these principles it was sited in a landscape of great scenic beauty on an axis joining the Tuong Son and Don Son mountains in a plain between the Ma and Buoi rivers. The citadel buildings represent an outstanding example of a new style of south-east Asian imperial city.

Outstanding Universal Value

Brief synthesis

The Citadel of Ho Dynasty built in 1397, composed of the Inner Citadel, La Thanh Outer Wall and the Nam Giao Altar covers 155.5 ha, surrounded by a buffer zone of 5078.5 ha. It is located in accordance with geomantic principles in a landscape of great scenic beauty between the Ma and Buoi rivers in Vinh Loc district, Thanh Hoa province of Viet Nam. The Inner Citadel constructed of large limestone blocks represents a new development of architectural technology and adaptation of geomantic city planning in an East Asian and South-east Asian context. It demonstrates the use of architectural elements in terms of space management and decoration designed for a centralized imperial city in order to show a concept of royal power, based on the adoption of the Confucian philosophy within a predominantly Buddhist culture. Being the capital of Viet Nam from 1398 to 1407 and also the political, economic and cultural centre of North Central Viet Nam from the 16th to the 18th century, it bears exceptional testimony to a critical period in Vietnamese and South-east Asian history when traditional kingship and Buddhist values were giving way to new trends in technology, commerce and centralized administration.

Criterion (ii): The property exhibits Chinese Confucianism influence on a symbol of regal centralized power in the late 14th – early 15th century. It represents new developments in architectural style with respect to technology and, in adapting pre-existing geomantic city planning principles in an East Asian and South-east Asian context, makes full use of the natural surroundings and incorporated distinctly Vietnamese and East and Southeast Asian elements in its monuments and landscape.

Criterion (iv): The Ho Citadel is an outstanding example of an architectural ensemble in a landscape setting which illustrates a flowering of pragmatic Neo-Confucianism in late 14th century Viet Nam, at a time when it was spreading throughout East Asia to become a major philosophical influence on government in the region. The use of large blocks of stone testifies to the organizational power of the Neo-Confucian state, and the shift in the main axis distinguishes the Citadel layout from the Chinese norm.

Complex of Hué Monuments

Established as the capital of unified Viet Nam in 1802, Hué was not only the political but also the cultural and religious centre under the Nguyen dynasty until 1945. The Perfume River winds its way through the Capital City, the Imperial City, the Forbidden Purple City and the Inner City, giving this unique feudal capital a setting of great natural beauty.

 

Outstanding Universal Value

Brief synthesis

The Complex of Hue Monuments is located in and around Hue City in Thua Thien-Hue Province in the geographical centre of Vietnam and with easy access to the sea. Established as the capital of unified Vietnam in 1802 CE, Hue was not only the political but also the cultural and religious centre under the Nguyen Dynasty, the last royal dynasty of Vietnamese history, from 1802 to 1945 CE.

The plan of the new capital is in accordance with ancient oriental philosophy, and respected the physical conditions of the site.

The Ngu Binh Mountain (known as the Royal Screen) and the Perfume River, which runs through the city, give this unique feudal capital an entire setting of great natural beauty as well defining its symbolic importance. The site was chosen for a combination of natural features – hills representing a protective screen in front of the monuments or taking the role of “a blue dragon” to the left and “a white tiger” to the right – which shield the main entrance and prevent the entry of malevolent spirits.  Within this landscape, the main features of the city are laid out.

The structures of the Complex of Hue Monuments are carefully placed within the natural setting of the site and aligned cosmologically with the Five Cardinal Points (centre, west, east, north, south), the Five Elements (earth, metal, wood, water, fire), and the Five Colours (yellow, white, blue, black, red).

The central structure is the Hue Citadel area which was the administrative centre of southern Viet Nam during the 17th and 18th centuries CE. Within the Hue Citadel were located not only administrative and military functions of the Empire, but also the Imperial Residence, the Hoang Thanh (Imperial City), the Tu Cam Thanh (Forbidden Purple City) and related royal  palaces.

Tran Binh Dai, an additional defensive work in the north-east corner of the Capital City, was designed to control movement on the river. Another fortress, Tran Hai Thanh, was constructed a little later to protect the capital against assault from the sea.

Outside the Capital City there are several associated monuments of importance. In the outlying areas were located important ritual sites related to the spiritual life of the dynasty such as the Van Mieu (Temple of Literature), the Dan Nam Giao (Esplanade of Sacrifice to the Heaven and Earth), the Ho Quyen (Royal Area), the Den Voi Re (Temple of the Roaring Elephant), and the Chua Thien Mu (Celestial Lady Pagoda).  Further upstream, arranged along the Perfume River were the tombs of the dynasty’s emperors.

The Complex of Hue Monuments is a remarkable example of the planning and construction of a complete defended capital city in a relatively short period in the early years of the 19th century CE.  The integrity of the town layout and building design make it an exceptional specimen of late feudal urban planning in East Asia.

Criterion (iv):   The Complex of Hue Monuments is an outstanding example of an eastern feudal capital.

Outstanding Universal Value

Brief synthesis

Hoi An Ancient town is located in Viet Nam’s central Quang Nam Province, on the north bank near the mouth of the Thu Bon River. The inscribed property comprises 30 ha and it has a buffer zone of 280 ha. It  is an exceptionally well-preserved example of a small-scale trading port active the 15th to 19th centuries  which traded widely, both with the countries of Southeast and East Asia and with the rest of the world. Its decline in the later 19th century ensured that it has retained its traditional urban tissue to a remarkable degree.

The town reflects a fusion of indigenous and foreign cultures (principally Chinese and Japanese with later European influences) that combined to produce this unique survival.

The town comprises a well-preserved complex of 1,107 timber frame buildings, with brick or wooden walls, which include architectural monuments, commercial and domestic vernacular structures, notably an open market and a ferry quay, and religious buildings such as pagodas and family cult houses. The houses are tiled and the wooden components are carved with traditional motifs.  They are arranged side-by-side in tight, unbroken rows along narrow pedestrian streets. There is also the fine wooden Japanese bridge, with a pagoda on it, dating from the 18th century. The original street plan, which developed as the town became a port, remains. It comprises a grid of streets with one axis parallel to the river and the other axis of streets and alleys set at right angles to it. Typically, the buildings front the streets for convenient customer access while the backs of the buildings open to the river allowing easy loading and off-loading of goods from boats.

The surviving wooden structures and street plan are original and intact and together present a traditional townscape of the 17th and 18th centuries, the survival of which is unique in the region. The town continues to this day to be occupied and function as a trading port and centre of commerce. The living heritage reflecting the diverse communities of the indigenous inhabitants of the town, as well as foreigners, has also been preserved and continues to be passed on. Hoi An Ancient Town remains an exceptionally well-preserved example of a Far Eastern port.

Criterion (ii): Hoi An is an outstanding material manifestation of the fusion of cultures over time in an international commercial port.

Criterion (v): Hoi An is an exceptionally well-preserved example of a traditional Asian trading port.

My Son Sanctuary

Between the 4th and 13th centuries a unique culture which owed its spiritual origins to Indian Hinduism developed on the coast of contemporary Viet Nam. This is graphically illustrated by the remains of a series of impressive tower-temples located in a dramatic site that was the religious and political capital of the Champa Kingdom for most of its existence.

 

Outstanding Universal Value

Brief synthesis

During the 4th to 13th centuries there was a unique culture on the coast of contemporary Vietnam, owing its spiritual origins to the Hinduism of India. This is graphically illustrated by the remains of a series of impressive tower temples in a dramatic site that was the religious and political capital of the Champa Kingdom for most of its existence.

My Son Sanctuary dates from the 4th to the 13th centuries CE. The property is located in the mountainous border Duy Xuyen District of Quang Nam Province, in central Viet Nam. It is situated within an elevated geological basin surrounded by a ring of mountains, which provides the watershed for the sacred Thu Bon river. The source of the Thu Bon river is here and it flows past the monuments, out of the basin, and through the historic heartland of the Champa Kingdom, draining into the South China Sea at its mouth near the ancient port city of Hoi An. The location gives the sites its strategic significance as it is also easily defensible.

The tower temples were constructed over ten centuries of continuous development in what was the heart of the ancestral homeland of the ruling Dua Clan which unified the Cham clans and established the kingdom of Champapura (Sanskrit for City of the Cham people) in 192 CE. During the 4th to 13th centuries CE this unique culture, on the coast of contemporary Viet Nam, owed its spiritual origins to the Hinduism of the Indian sub-continent. Under this influence many temples were built to the Hindu divinities such as Krishna and Vishnu, but above all Shiva. Although Mahayan Buddhist penetrated the Cham culture, probably from the 4thcentury CE, and became strongly established in the north of the kingdom, Shivite Hinduism remained the established state religion.

The monuments of the My Son sanctuary are the most important constructions of the My Son civilization. The tower temples have a variety of architectural designs symbolizing the greatness and purity of Mount Meru, the mythical sacred mountain home of Hindu gods at the center of the universe, now symbolically reproduced on Earth in the mountainous homeland of the Cham people. They are constructed in fired brick with stone pillars and decorated with sandstone bas-reliefs depicting scenes from Hindu mythology. Their technological sophistication is evidence of Cham engineering skills while the elaborate iconography and symbolism of the tower-temples give insight into the content and evolution of Cham religious and political thought.

The My Son Sanctuary is a remarkable architectural ensemble that developed over a period of ten centuries. It presents a vivid picture of spiritual and political life in an important phase of the history of South-East Asia.

The monuments are unique and without equal in Southeast Asia.

Criterion (ii): The My Son Sanctuary is an exceptional example of cultural interchange, with an indigenous society adapting to external cultural influences, notably the Hindu art and architecture of the Indian sub-continent.

Criterion (iii): The Champa Kingdom was an important phenomenon in the political and cultural history of South – East Asia, vividly illustrated by the ruins of My Son.
