There are a total of ten main majestic gates leading to the Imperial City of Hue, which can be divided into two main parts excluding houses and mansions: The Citadel and The Forbidden City. The former served to protect the important palaces inside while the latter was where the emperor and the royal family stayed as well as the court’s workplace. All the typically traditional Eastern architectures including majestic palaces, tombs and museums stand accordantly together to make an utmost amusing attraction right in the heart of Vietnam.
The remaining buildings in the Citadel have been carefully restored. Much of the land that used to be the Purple Forbidden City, however, is today just rice fields.
