Quang Trị
Quang Trị is a province in the North Central Coast region of Vietnam, north of the former imperial capital of Hue.Located in the North Central Coast region of Vietnam, Quang Trị Province is surrounded by Quang Binh Province to the north; Thua Thien-Hue Province to the south; Savannakhet Province, in Laos, to the west; and the South Bien Dong Sea to the east, with 75 kilometres (47 mi) of coast. Except for the narrow piedmont coastal plains, the terrain is dominated by hills and the Annamite Mountains.A major feature of the town is the Quang Trị Citadel, built in 1824, as a military bastion during the 4th year of the reign of Minh Mạng. It is an example of Vauban architecture and it later became the administrative head office of the Nguyen dynasty in Quang Trị Province (1809–1945).
