The walled enclosure was made up of palaces, fortresses, the current citadel and a forbidden city that served as the private residence of the emperors. One of the few original buildings that remain in the complex is the North Gate or Chinh Bac Mon, one of the 4 entrances to enter the old Imperial City, its construction dates back to 1802. The most important building preserved in foot is the Flag Tower, 33 meters high, it is one of the symbols of Hanoi, it was built in 1812 when the capital had already moved to Hue, so it is not considered part of the original complex. It is well known for its architectural heritage. It was declared a World Heritage Site by UNESCO in 2010. Its size and style are similar to those of the Forbidden City in Beijing. Its royal palaces and most of its structures were left in various states of disrepair in the late 19th century with the upheaval of the French conquest of Hanoi. In the 20th century many of the remaining structures were demolished. Remains of the imperial city were discovered on the site of the former Ba Dình City Hall when the structure was demolished in 2008 to make way for a new Parliament building. Several archaeological remains discovered were taken to the National Museum where they are exhibited.
