Imperial Citadel of Thang Long-a historic building marking the independence of HN from Chinese reign

The Imperial Citadel of Thăng Long is a complex of historic buildings associated with the history of Vietnam located in the centre of Hanoi, Vietnam. Its construction began in 1010 and was completed in early 1011 under the reign of Emperor Lý Thái Tổ of the Lý 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.
