Hue’s Imperial Citadel was the seat of Vietnam’s last royal dynasty, the Nguyen, and the walled palace complex where the country’s final emperor read out his abdication in 1945, ending two thousand years of monarchy. Its gates, throne halls and the tombs strung along the Perfume River form one of Vietnam’s largest surviving royal landscapes.
At a glance
The Imperial Citadel of Hue is built as three concentric enclosures modelled on Beijing’s Forbidden City. The outer Kinh Thanh, or Capital Citadel, encloses the whole city and its garrison; within it sits the walled Imperial City, or Hoang Thanh, home to the throne halls and ceremonial courts; and at its heart lies the Forbidden Purple City, the private quarters once reserved for the emperor, his family and his household staff.
The complex was the ceremonial and administrative centre of the Nguyen dynasty for almost a century and a half, and it was on the platform above its main gate that the last Vietnamese emperor formally gave up the throne in 1945.
Key facts
- Founded: construction of the citadel walls began in 1804 under Emperor Gia Long, founder of the Nguyen dynasty.
- Ngo Mon Gate: built in 1833 by Emperor Minh Mang as the main southern entrance, 57 metres wide, with a five-gate structure topped by the Ngu Phung, or Five Phoenix, Pavilion.
- Abdication: on 25 August 1945, Emperor Bao Dai read his abdication from the pavilion above Ngo Mon Gate and handed the imperial seal and sword to a Viet Minh representative, ending the Nguyen dynasty.
- Nine Dynastic Urns: nine bronze urns cast in 1837 under Minh Mang, each weighing around two tonnes and engraved with the mountains and rivers of Vietnam, one for each of the Nguyen emperors reigning by that date.
- Recognition: the citadel was inscribed as a UNESCO World Heritage Site in 1993; the associated court music tradition, Nha Nhac, was separately added to UNESCO’s Representative List of the Intangible Cultural Heritage of Humanity in 2003.
History
Gia Long, who founded the Nguyen dynasty in 1802 after defeating the Tay Son rebels, chose Hue as his capital for its central position between north and south, moving the seat of power there from Hanoi. Construction of the citadel walls began in 1804, and his successor Minh Mang expanded the complex through to 1833, adding the Ngo Mon Gate and completing the Forbidden Purple City. The Nguyen court drew heavily on Chinese imperial models, and its emperors styled themselves in the tradition of the Son of Heaven.
French forces captured Hue in 1883, and under the Treaty of Hue the city became the seat of a French protectorate over Annam, with the Nguyen emperor retaining only nominal, ceremonial authority. Japanese forces displaced the French in Vietnam in 1945, and Emperor Bao Dai briefly declared independence before abdicating at Ngo Mon Gate on 25 August 1945, handing power to the Viet Minh and ending the Vietnamese monarchy.
During the Vietnam War, Hue was occupied by North Vietnamese and Viet Cong forces for several weeks during the Tet Offensive of 1968, in one of the war’s bloodiest episodes. The Forbidden Purple City was largely destroyed in the fighting, and much of the citadel has since been the subject of ongoing restoration. Hue’s historic monuments were inscribed as a UNESCO World Heritage Site in 1993.
What you see
Visitors enter through the Ngo Mon Gate, whose upper pavilion once served as a platform for imperial proclamations, including Bao Dai’s abdication. Beyond it stands the Thai Hoa Palace, the Supreme Harmony throne hall first built under Gia Long and rebuilt by Minh Mang, its interior lined with red lacquered columns carrying gold dragon motifs. Nearby stand the Nine Dynastic Urns, cast in bronze in 1837 and still bearing their engraved landscapes.
The Forbidden Purple City, once the private preserve of the emperor’s household, was largely destroyed during the 1968 fighting and survives today mainly as a site of ongoing restoration rather than a complete structure. The restored Royal Theatre, Duyet Thi Duong, originally built in 1826, hosts performances of Nha Nhac court music in something close to its original architectural setting.
Further out, along the Perfume River south of the city, lie the tombs of several Nguyen emperors, including Minh Mang, Tu Duc, Khai Dinh, Gia Long, Thieu Tri, Dong Khanh and Duc Duc. The Tu Duc tomb, built over sixteen years, is the most elaborate, set among lakes and dozens of structures. The Khai Dinh tomb, built in the 1920s, is strikingly different, mixing French Art Deco concrete construction with traditional Vietnamese ornamental motifs.
Practical information
- Getting in: tickets, current opening arrangements and any restrictions on the Forbidden Purple City restoration areas are best checked through the site’s official heritage authority before visiting.
- Nha Nhac performances: court music is staged at the Royal Theatre inside the Imperial City; times and booking should be confirmed with the theatre or the local tourism office.
- Royal Tombs: the tombs lie some distance south of the citadel along the Perfume River and are generally visited as a separate excursion.
Getting there
The citadel sits within the city of Hue, in Thua Thien Hue Province, at approximately 16.4698° N, 107.5796° E. It is reached on foot or by local transport from central Hue; onward travel to the Perfume River tombs, which lie further south, is best arranged through a local operator or the city’s tourism office.
