Tourists Entering The Citadel Through One Of It`s Entrance Gates, Hue, Vietnam Editorial Photo

Pictured are tourists on motorcycles and one in a cyclo entering the Citadel through an entrance gate in the outer wall. A cyclo is a three wheeled bicycle taxi. The Imperial Citadel is magnificent, with defensive walls 2 kilometres long and 2 metres thick, including forts and ramparts all surrounded by a wide moat. Within these walls, the Imperial Palace was built as a citadel within the citadel, with another moat and set of walls surrounding it. Again, within the palace walls was another walled enclosure known as the Purple Forbidden City, which was home to the Imperial Family. The Citadel was built by Nguyen Anh, the first to take control of Vietnam and unify it as one country, beginning the Nguyen Dynasty and proclaiming himself Emperor Gia Long.
