Imperial City, Hue

The Imperial City is a walled fortress and palace in the city of Hue, the former imperial capital of Vietnam.


The grounds of the Imperial City are protected by fortified ramparts 2 kilometers by 2 kilometers, and ringed by a moat. The water in the moat is routed from the Huong River through a series of sluice gates. This enclosure is the Citadel. Inside the Citadel is the Imperial City, with a perimeter wall some 2.5 kilometers in length. Within the Imperial City is the Purple Forbidden City, a term similar to the Forbidden City in Beijing. Access to the innermost enclosure is restricted to the Nguyen imperial family.


In June 1802 Nguyen Anh took control of Vietnam and proclaimed himself Emperor Gia Long. His rule was recognized by China in 1804. Gia Long consulted with geomancers to decide which was the best place for a new palace and citadel to be built. After the geomancers had decided on a suitable site in Hue, building began in 1804. Thousands of workers were ordered to produce a wall and moat, 10 kilometers long. Initially the walls were earthen, but later these earthen walls were replaced by stone walls, 2 meters thick.

The citadel was oriented to face the Huong River to the east. This was different from the Forbidden City in Beijing, which faces south. The Emperor's palace is on the east side of the citadel, nearest the river. A second set of walls and a second moat was constructed around the Emperor's palace. Many more palaces and gates and courtyards and gardens were subsequently added. The reigns of the last Vietnamese Emperors lasted until the mid-1900s. At the time, the Purple Forbidden City had many buildings and hundreds of rooms. It suffered from termite and cyclone damage, but was still very impressive. Many bullet holes left over from the Vietnam War can be observed on the stone walls.

In the early morning hours of January 31, 1968, as part of the Tet Offensive a Division-sized force of North Vietnamese Army and Viet Cong soldiers launched a coordinated attack on Huế seizing most of the city. During the initial phases of the Battle of Hue, due to Hue's religious and cultural status, US troops were ordered not to bomb or shell the city, for fear of destroying the historic structures, but as casualties mounted in house-to-house fighting these restrictions were progressively lifted and the fighting caused substantial damage to the Imperial City. Out of 160 buildings only 10 major sites remain because of the battle, such as the Thai Hoa and Can Thanh temples, Thế Miếu, and Hien Lam Cac. The city was made a UNESCO site in 1993. The buildings that still remain are being restored and preserved. The latest and so far the largest restoration project is planned to conclude in 2015.
