Imperial Citadel

You are standing at the entrance of one of Hanoi’s most important historical sites: the Imperial Citadel of Thăng Long. Its name, meaning “Rising Dragon,” dates back to 1010, when King Lý Thái Tổ established the city as the center of power. The citadel was built on older remains from earlier periods of Chinese rule. For nearly a thousand years, under the Lý, Trần, and Lê dynasties, it was the political heart of Vietnam, home to imperial palaces, ceremonial spaces, and centers of decision-making. As you explore, you’ll notice architecture shaped by Chinese and Cham influences, alongside local Red River Delta traditions, visible in the layout, foundations, and surviving buildings. Archaeological excavations in the early 2000s uncovered numerous palace remains and defensive walls, highlighting the citadel’s role as a political, cultural, and historical center of Vietnam. The site also played a part in modern history: during the Vietnam War, an underground bunker called D67 served as a military headquarters and is now open to visitors. Designated a UNESCO World Heritage Site in 2010, the Imperial Citadel of Thăng Long stands as a testament to the continuity of Vietnam’s state and the pivotal moments that shaped its history.
