The Flag Tower of Hanoi is a tower in Hanoi, Vietnam, which is one of the symbols of the city and once a part of the Hanoi Citadel, a World Heritage Site. Its height is 33.4 m. The tower is considered to have been built in 1805 or 1812 during the Nguyen dynasty as an observation post to the Hanoi Citadel. Unlike many other structures in Hanoi, it was not destroyed during the French invasion, and was continuously used as a military post. From 1956 to 2024, the Hanoi Flag Tower was located within the grounds of the Vietnam Military History Museum, and now belongs to the Imperial Citadel of Thang Long, situated on Dien Bien Phu Street, Ba Dinh District.
