Hue Citadel, The Imperial City
The walled fortress and palace in the city of Hue was once the administrative capital of Southern Vietnam. The Citadel grounds are surrounded by a moat fed by the Perfume River and inside the Citadel is the Imperial City which houses the Purple Forbidden City inside its perimeter. The vast complex was once the administrative centre of southern Vietnam during the 17th and 18th Centuries and, although the complex is in disrepair and restoration has been slow, it’s still absolutely worth a visit when in Hue.
