Hue is located in Thua Thien prefecture and is in the central part of Vietnam. Located 660 km from Ha Noi and 1080 km from Saigon, Hue has always been considered the fulcrum of Vietnam's two rice baskets, the Red river delta and the Mekong delta. Hue became the name of Vietnam's most well known ancient capital because of the local mispronunciation of the word Hoá in Thuân Hoá.

Since the 16th century, Thuan Hoa, due to its strategic location, has been a very prosperous area. The Nguyen Lord chose this area to be their headquarters. Nguyen Anh made it Vietnam's capital city in 1802 after he defeated the Tay Son and ascended to the throne with the name Gia Long. King Gia Long (1762-1819) was credited for building and fortifying Hue from the very beginning. Since then, successive king of the Nguyen Dynasty has added to the foundation set by his predecessors.

Cultural Heritage

Although Hue has sustained much damage from natural disasters and wars, the city and most of the architecture remain. As a capital city, Hue is relatively young since the Nguyen dynasty only ended some 50 years ago (1802-1945). Of the ancient capitals in Vietnam, Hue is the only one that still has the intact appearance of a complex of the monarchic capital consisting of walls, palaces, and royal tombs. Consequently, Hue is among Vietnam's most valued national treasure in terms of history and heritage

In 1981, after visiting Hue, Mr. Amadou-Mahtar-M'Bow, then Director General of UNESCO proclaimed Hue to be "a masterpiece of urban poetry". On December 11, 1993, UNESCO's Director General, Federico Mayor acknowledged the Complex of Monuments of Hue to be a World Culture Heritage.

Based on the ancient practice of geomancy, the Citadel was designed and planned around the natural elements in the area north of the Perfume river. The complex faces southeast, taking Mount Ngu Binh (Royal Screen Mount) as a natural screen. Two islets in the Perfume river, Ta Thanh Long (Left Green Dragon) and Huu Bach Ho (Right White Tiger) play the role of sentinels for the Citadel. The construction of the Citadel took place from 1805 to 1832.

The Citadel is a square enclosure with a circumference of 10,000 m, a height of 6.6 m and a thickness of about 21 cm. The center of the wall is packed with dirt while the outer shell is built with bricks. There are ten gates to access the Citadel each with a two story watch tower. The gates are named according to their direction of exit. The southeastern gate is also known as Thuong Tu gate, The Eastern gate is also called Cua Dong Ba etc...The Citadel was built to accommodate 24 bastions with over 400 canons.
