40 kilometers to the West of Hoi An is My Son Sanctuary - Vietnam’s most important site of the ancient kingdom of Champa. Between the 4th and 13th century a unique culture which owed its spiritual origins to Indian Hinduism developed on the coast of then contemporary Vietnam. This is graphically illustrated by the remains of a series of impressive tower-temples located in a dramatic site that was the religious and political capital of the Champa Kingdom for most of its existence. Located in the heart of a beautiful valley and surrounded by high mountains ranges My Son was named a Cultural Heritage site by UNESCO in 1999. Originally built with wood, they were completely destroyed by fire in the 6th century and restored in the 7th century by Sambhuvarman who rebuilt the temples with locally made bricks. Up to the 13th century, more than 70 similar temples were built, establishing My Son as a sanctuary of Hinduism in the Champa Kingdom. The My Son Sanctuary is a remarkable architectural ensemble that developed over a period of ten centuries. It presents a vivid picture of spiritual and political life in an important phase of the history of South-East Asia.
