This tower marked the beginning point of the southerly central axis, followed by Doan Mon Gate and Kinh Thien Palace – the central and most important point.
The Flag Tower includes three-tier basement and a column three storeys and a tower. The truncated square pyramid-shaped storeys are faced with bricks. The first tier has the length of each side of 42.5m, the height of 3.1m and two brick staircases. 
Hanoi Flag Tower is one of the rare architectural works in Hanoi Citadel that was fortunate enough to not be destroyed by the French domination administration between 1894 and 1897.

Hanoi Flag Tower was used as an observation tower by French Army. In American war, it was also an observation tower of Hanoi’s air defence forces. At that time, from the top of the tower, it was possible to observe the whole Hanoi and the suburb.
On October 10th, 1954, the red flag with yellow star, the National Flag, flied on the top of Hanoi Flag Tower for the first time which was recognized as the historical monument in 1989. 
That day, the people jubilantly welcomed the Festival of Victory, the day Hanoi became completely liberated. The people marched towards Hanoi Flag Tower, waiting for a historic moment: the hoisting ceremony of National Flag on the top of Hanoi Flag Tower.

At 3pm on October 10th, 1954, the siren of Hanoi Opera House wailed for a while. And then, while the military band was playing the national anthem under the direction of Comrade Dinh Ngoc Lien, the National Flag was gradually hoisted. For the first time, the red flag with yellow star, the National Flag, flied on the top of Hanoi Flag Tower. 
Until now, Hanoi Flag Tower is nearly 200 years old. When Democratic Republic of Vietnam was born, the image of Hanoi Flag Tower was solemnly printed on the first coins of Vietnam State Bank.
For more than half of a century, plugged on the top of Hanoi Flag Tower, the red flag with yellow star has flied in the sky of Thang Long – Hanoi Capital of thousand years tradition as a symbol of glory and pride of an independence and freedom Vietnam.
