Complex of Hue Monuments lies along the Perfume River in Hue City and some adjacent areas of Thua Thien Hue Province. Hue City constitutes the cultural, political and economic centre of the province, and was the old imperial city of Vietnam under the Nguyen Dynasty from 1802 to 1945.
Since 1306, after the wedding of the princess Huyen Tran of the Tran Dynasty with Che Man, the Cham King, the territories of Chau O and Chau Ly (comprised of Quang Tri, Thua Thien – Hue and part of Northern Quang Nam today) took the name of Thuan Hoa. In the second half of the 15th century, under the reign of King Le Thanh Tong, the name of “Hue” appeared for the first time. In 1636, the residence of the Nguyen Lords was settled at Kim Long (Hue). In 1687, it was transferred to Phu Xuan – where is the Citadel today. Early in the 18th century, Phu Xuan became the political, economic and cultural centre of the southern part of Vietnam. Then, from 1788 to 1801, it became the capital of the Tay Son Dynasty.
From 1802 to 1945, Hue was the capital of unified Vietnam under the reign of the 13 Nguyen Kings. During these years, architectural works of a high cultural and historic value were built: the Citadel, especially the Imperial City (including 253 constructions), 7 Royal tomb compound of 9 kings of the Nguyen Dynasty, the Esplanade of Nam Giao, the Ho Quyen arena and the Hon Chen Temple.
