A certificate “National Historical Relic” was handed over to the management board of the Thang Long Royal Citadel Relic Complex at a ceremony in Hanoi on February 10.

Thang Long was considered the biggest and oldest royal city and had the most strategic position in the history of Vietnam. In the Edict on the Transfer of the Capital issued in 1010, King Ly Thai To decided to move the capital from Hoa Lu (in Ninh Binh province) to Thang Long (in Hanoi). The royal complex was built, but due to various causes, it was damaged and buried deep under the ground.
