The site is located 69km southwest of Da Nang, and approximately 10km from the historic town of Tra Kieu. Tra Kieu ( simhapura) was the first capital of champa serving in that capacity from the 4th through 8th century. It comprises many champa temples, in valley roughly 2km wide, surrounded by two mountain ranges. It is the former capital of the ancient Cham civilization that ruled Central Vietnam from the second to the thirteenth century. Their religion was primarily derived from Indian Hinduism. My Son is considered to be one of the best-preserved Cham structures in Vietnam.
