Nguyen dynasty’s royal tomb is one of the important factors in Hue architectural complex – the World Cultural Heritage recognized in 1993 by UNESCO.
. Mentioning Hue, people might think of ramparts, royal palace, esplanade, pagoda and large royal tombs – the greatest architectural structures of the traditional art harmonizing with nature. “As the works of the working population as well as the most skilful handicraftsmen nationwide, those architectural structures express original variations on a definite theme. Each royal tomb, with its own characteristics, is a perfect achievement of the landscape architecture; and may leave in tourists’ heart different special emotions. Gia Long tomb situated in a large natural forest arouses mighty but peaceful impression. Minh Mang tomb is solemn, and Tu Duc tomb gives tourists the poeticism.”
