Hanoi Flag Tower is a special historical structure and has the most majestic scale in the Thang Long Imperial Citadel complex. Not only is it a symbol of Hanoi, but the Flag Tower is also a historic relic. This work is considered a “historical witness” to the resilience and indomitability of the local people during the glorious resistance war against the French.

General information about Hanoi Flag Tower

The Hanoi Flag Tower was built during the Nguyen Dynasty, from 1805 to 1812, at the same time as the Hanoi Citadel. The project was built as a tower, serving as an observation tower for the inner and suburban areas at the time. This is also why the French colonial government did not demolish this structure between 1894 and 1897.

During the resistance war against the US, the Flag Tower was guarded and used by Hanoi Air Defense troops for the same purpose. In 1945, after the success of the August Revolution, the red flag with a yellow star was first hoisted atop the Flag Tower. In 1954, the resistance war against the French colonialists was a complete victory, and the National Flag once again flew.
