The imperial city of Thang Long is situated in the historic center of Hanoi. Thang Long was actually the historic name of Hanoi before colonialism. It is composed of two sites; the first one is a complex comprising different nice buildings and the citadel with its famous tower. The other one, situated very close (cross the road), is an archeological park where buildings and antiquities are getting excavated. This place is interesting to see how people excavate things and how deep in the ground it can be. The imperial city has more than ten centuries of history and several dynasties used to live in. It was also welcoming ritual ceremonies.

The site is not well indicated. It is situated just close to the statue of Lenin, midway between the old quarter and Ho Chi Minh mausoleum. The entrance is free but take care of the time.
