Hue

Hue is the third largest city of Vietnam, with great historical and cultural significance as the capital of the Empire of Annam, specifically the Nguyen Dynasty starting with King Nguyen Anh in 1802. It is in Thua Thien prefecture, of north-central Vietnam. 660 km from Hanoi and 1080 km from Saigon, it is a geographical center, also providing access to the Central Highlands.

Many of the imperial and colonial structures survive, and on December 11, 1993, UNESCO declared its Complex of Monuments of Hue to be a World Cultural Heritage.
