The Thang Long Imperial Citadel was established in the 11th century by the Ly Viet Dynasty, symbolizing the independence of Dai Viet. It was built atop the remnants of a 7th-century Chinese fortress on land reclaimed from the Red River Delta in Hanoi. For nearly 13 centuries, it served as a continuous center of regional political power. The structures of the Imperial Citadel and the artifacts found at the 18 Hoang Dieu Archaeological Site showcase a distinctive Southeast Asian culture unique to the lower Red River Valley, situated at the intersection of influences from northern China and the ancient Kingdom of Champa to the south.
