The Thang Long Imperial Citadel, located at the heart of Vietnam’s capital city Hanoi, has borne witness to the long history of the country as it has been a continuous seat of political power for almost thirteen centuries.
The Thang Long (Ascending Dragon) Imperial Citadel was built in the 11th century by the Vietnamese Ly Dynasty (1010-1225), to mark the independence of the Dai Viet, as Vietnam was known at that time.
It was built on the remains of a Chinese fortress dating from the seventh century, on drained land reclaimed from the Red River Delta in Hanoi. The Imperial Citadel and the remains of the 18 Hoang Dieu archaeological site reflect a unique South-East Asian culture, specific to the lower Red River Valley, cites the introduction of the United Nations Educational, Scientific and Cultural Organization (UNESCO) on its website.
