My Son became the most important Cham intellectual and religious centre under King Bhadravarman in the 4th century and was occupied until the 13th century. It is set in a verdant valley which is 70 km south-west of Da Nang City. Here architectural traces of 70 structures have been found, but only 20 structures survived repeated wars. They are typical structures of Cham's architecture from the 7th to the 13th centuries. My Son is now restored.
