The Citadel (Dai Noi)

Constructed in 1804, this massive fortress designed for the Gia Long Emperor, is surrounded by a zigzag moat and defensive barrier that’s 21 meters thick. But visitors to this citadel-in-a-citadel-in-a-citadel won’t need to swim across rivers or scale towering walls to get a look inside. The Imperial Enclosure is accessible by crossing one of the 10 pedestrian bridges into the once royal land. Pass through Ngo Mon (Noon) Gate, once reserved for those in power, then wander through Flag Tower (Cot Co) and stare up at the nation’s tallest flagpole before weaving through the Nine Dynastic Urns representing different Nguyen kings.

Practical Info:

The Citadel is an easy walk from numerous hotels in Hue and also accessible by bike. Visitors should wear comfortable shoes or consider hiring a rickshaw to experience the entire complex. Open daily from 7:30 a.m. until 5 p.m.
