Besides the famous places, landscapes, cultural and historical relics of Hanoi, the flagpole of Hanoi is still considered as one of the most prominent and solid symbols of the capital. Hanoi flagpole, also known as Ky Dai, is one of the rare buildings in the Imperial Citadel of Thang Long that is intact, enduring with time, bearing a majestic and quiet appearance. Not only that, this special work is also a place to witness the historical ups and downs of the land of Hanoi, with a sacred meaning when the first red flag with yellow star was hoisted here.
