Located in the Annamite mountains, it features rugged karst landscapes, deep caves—including the vast Xe Bang Fai Cave—as well as rich biodiversity and associated local traditional use. The park lies within the Indo-Burma biodiversity hotspot, home to over 1,500 plant and 536 vertebrate species, including many endemics and globally threatened species like the Red-Shanked Douc Langur and Sunda Pangolin. Unique species such as the Lao Rock Rat and Giant Huntsman Spider also inhabit the area. Its diverse ecosystems span lowland forests to high-altitude karst habitats.”

Vietnam - Ha Long Bay - Cat Ba Archipelago

Extension Update: "Ha Long Bay, in the Gulf of Tonkin, includes some 1,600 islands and islets, forming a spectacular seascape of limestone pillars. The extension of the property comprises a multitude of limestone islands and towering limestone pillars rising from the sea, with eroded notches, arches and caves creating a picturesque and beautiful landscape. Seven key ecosystem types are found here and the area is home to threatened endemic species such as the Cat Ba Langur (Trachypithecus poliocephalus), the Cat Ba Tiger Gecko (Goniurosaurus Catbaensis), and the Asian Small-clawed Otter (Aonyx cinerea)."

"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."

Vietnam - The Central Sector of the Imperial Citadel of Thang Long

"The Thang Long Imperial Citadel has become the 900th site to be inscribed on UNESCO’s World Heritage List. The Citadel was built in the 11th century by the Ly Viet Dynasty, marking the independence of the Dai Viet. It was constructed on the remains of a Chinese fortress dating from the 7th century, on drained land reclaimed from the Red River Delta in Hanoi. It was the centre of regional political power for almost 13 centuries without interruption. The Imperial Citadel buildings and the remains in the 18 Hoang Dieu Archaeological Site reflect a unique South-East Asian culture specific to the lower Red River Valley, at the crossroads between influences coming from China in the north and the ancient Kingdom of Champa in the south."
