About Flag Tower of Hanoi

The Flag Tower of Hanoi (Cột cờ Hà Nội) is one of the symbols of the city and was once part of the Hanoi Citadel, a World Heritage Site. It is thought to have been built in 1805 or 1812 under the Nguyen dynasty as the citadel's observation post. Unlike many structures in Hanoi it survived the French invasion and stayed in military use. Today it belongs to the Imperial Citadel of Thang Long, on Dien Bien Phu Street in Ba Dinh District. It rises on three tiers, with a spiral staircase inside the tower.
