Midway between Hanoi and Ho Chi Minh City lies the city of Hue. The former capital of the emperors of Vietnam, it is known for its beautiful imperial architecture, although a great deal of this was destroyed during the Tet offensive in 1968. The Perfume River forms the border between the city itself and the former ‘Forbidden Purple City’, the mighty Citadel. This ‘city within a city’ with its tombs, pagodas and lakes covered in lotus flowers was largely destroyed during the Vietnam War, but one can still see evidence of its former magnificence. Within easy reach of the city are the tombs of several of Vietnam’s emperors. Most interesting, perhaps, are the Tomb of Minh Mang and the Tomb of Tu Duc. The city also houses fine examples of Buddhist pagodas and other temples, such as the Thien Mu Pagoda.
