Flag Tower of Hanoi

The tower is considered to have been built in 1805 or 1812[1] 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 (1896-1897), and was continuously used as a military post.

It is now located in the Vietnam Military History Museum.

Cột cờ is composed of three tiers and a pyramid-shaped tower with a spiral staircase leading to the top inside it.

The words "Nghênh Húc" (English: "To welcome dawn's sunlight") are inscribed on the eastern door; the words "Hồi Quang" ("To reflect light") - on the western door and "Hướng Minh" ("Directed to the sunlight") - on the southern door.
