What is the Hue Imperial Citadel?
The Hue Imperial Citadel is the fortified capital of the Nguyen dynasty, on the north bank of the Perfume River. Emperor Gia Long began it in 1804, and his son Minh Mang finished it in 1832. A ring of walls and a moat encloses the Imperial City, and inside that sits the Forbidden Purple City, once reserved for the emperor and his household. UNESCO listed the complex in 1993. Adults pay 200,000₫ in 2026, and the main entrance is the Ngo Mon gate.

How the Citadel was built
Gia Long chose the site by geomancy, the traditional practice of reading landscape for good fortune, and had tens of thousands of labourers dig the moat and raise the walls. The outer walls were first earth. They were later rebuilt in brick and stone on the European military model of Vauban, the French engineer, which is why the Citadel looks more like a fortress than the Forbidden City in Beijing it was partly meant to echo.
The emperor did not live to see it finished. He died in 1820, and Minh Mang completed the work in 1832.
What happened in 1968
The Nguyen dynasty ended in 1945, when Emperor Bao Dai abdicated. In the decades after, the buildings suffered from typhoons, termites and neglect, and fighting in the late 1940s damaged them further.
In January 1968, during the Tet Offensive, North Vietnamese and Viet Cong forces took Hue and held the Citadel. Retaking it took about a month of heavy fighting, and the bombing and shelling flattened most of the inner palaces. Many of the Forbidden Purple City’s buildings never recovered, and parts of the site were rice fields for years afterwards. The Vietnam War page covers the battle in context.
What you can see today
Restoration has been going on for decades, so the Citadel is a patchwork. Allow for both the restored and the empty.
Ngo Mon gate
The main entrance, a gate with five passages and a pavilion on top from where the emperor reviewed ceremonies. The central passage was for the emperor alone.
Thai Hoa Palace
The throne hall across the first courtyard, where coronations and major audiences took place. It is the best-preserved large interior, with red and gold columns.
The Mieu and Hien Lam Cac
The temple to the Nguyen emperors holds altars to each ruler, and the nine bronze urns in front of it are one of the details most people photograph. The pavilion opposite is Hien Lam Cac.
The Forbidden Purple City
Much of this enclosure is now grass and foundations, with a few rebuilt halls. A signboard plan helps: it is easier to picture what was here once you can see where it stood.
Practical details for 2026
- Opening hours are about 6:30 to 17:30 in summer and 7:00 to 17:00 in winter, with evening visits on some nights. Check the posted times on the day.
- Allow two to three hours, or half a day if you also want the gardens and the museum.
- Go at opening or after 15:00. There is little shade and midday is hot.
- Cover your shoulders and knees in the temples. Sleeveless tops and short shorts may be refused at a few halls.
- Booths take cash, and tickets are also sold online.
Pairing it with the tombs
Most people take the Citadel on one day and the tombs on the next, using the combined ticket. The royal tombs and pagodas page explains which tombs to choose. For a longer trip from Hue, see Bach Ma National Park and the DMZ day trip. If you are coming from the coast, Hoi An and Da Nang are about three hours away by road.
