At the 23rd session of the World Heritage Committee held in 1999, My Son Relic Complex was recognized as a world cultural heritage site by UNESCO. It is an exceptional example of cultural interchange, with the introduction of Hindu architecture, and the only evidence of an Asian civilization that disappeared.
My Son Sanctuary is set in a small valley belonging to Duy Phu Commune, Duy Xuyen District, Quang Nam Province, 69km southwest of Da Nang City, 42 km from Hoi An City and 30km from the ancient Tra Kieu Citadel. It is a large complex of religious relics, including temples, shrines and towers of the capital of the Champa Kingdom. It is surrounded by high mountains with the only path between two hills that is blocked by a stream like a deep and large trench, hindering anyone from going into the holy land.
My Son Sanctuary was the worshipping place of the Champa Kingdom and the place where tombs of kings or members of royal families were built. It is one of the major religious sanctuaries of Hinduism in the Southeast Asian region.
