Huế Imperial City is a collection of significant architectural structures from the Nguyen dynasty, the final feudal dynasty in Vietnamese history. To this day, the complex still retains the imprints of a turbulent era marked by various changes.
Huế Imperial City – Traces of a Vibrant Feudal Era
The Hue Imperial Citadel was recognized by UNESCO as a World Cultural Heritage Site in December 1993. The entire complex comprises approximately 150 structures across 10 main functional zones: Gates & Ramparts, Outer Court, Forbidden Purple City, Thai Mieu, The Mieu, Phung Tien Palace, Dien Tho Palace, Truong Sanh Palace, Inner Citadel, and Co Ha Garden.

Currently, few structures remain within the Imperial City of Hue (the Inner Citadel), with around one-quarter having undergone restoration and reconstruction. Most other major structures have completely collapsed due to various factors.
The Construction Process of Huế Imperial City
When Lord Nguyen Hoang established his rule over Thuận Hoá land in 1558, the kingdom of Đàng Trong was founded. From then on, the Nguyen lords continuously built their power and expanded their territory. In 1802, Nguyen Anh defeated the Tay Son dynasty, ascended the throne as Emperor, adopted the regnal name Gia Long, and established the Nguyen dynasty, the final feudal dynasty in Vietnamese history.

Gia Long personally designed the plans for building the imperial capital from 1803. To construct Huế Imperial City, King Gia Long relocated 9 villages for redevelopment and regulated the natural river flows to establish a hydraulic system within the imperial city.

The history of constructing Huế Imperial City is divided into 4 periods. Period 1, from the early reign of Gia Long to the reign of Minh Mang, was the planning and construction period; Period 2, from the reign of Thieu Tri to the first half of Tu Duc's reign, involved repair and renovation activities for previously constructed buildings.

Period 3, from the latter half of Tu Duc's reign to the reign of Dong Khanh, was a period of maintenance, repair, and downsizing; Period 4, from the reign of Khai Dinh to the reign of Bao Dai, was a period of cultural architectural transformation between Vietnamese and French cultures and changes in construction techniques.
