Added to Unesco's World Heritage List in 2010, Hanoi's Imperial Citadel was the hub of Vietnamese military power for over 1000 years. Ongoing archaeological digs continue on-site, revealing remains of ancient palaces, grandiose pavilions and imperial gates. The main gate (Doan Mon) is named after one of the gates of the Forbidden City in Beijing. Further back is the imposing and colonnaded French Caserne de la Compagnie d'Ouvriers. At the rear is the Princess Pagoda (Hau Lau), which probably housed imperial concubines. The Imperial Citadel of Thăng Long is a complex of historic imperial buildings located in the centre of Hanoi, Vietnam. It is also known as Hanoi Citadel.
