My Son is a set of ruins from the ancient Cham Empire in the central coast of Vietnam. It is a UNESCO World Heritage Site.

My Son was built by the Champas who ruled Central Vietnam from c.200-c.1700 CE until annexed by the Vietnamese in the 19th century. Influenced by Hinduism, the Champas built temple complexes in Central Vietnam. 

The best-known and preserved temple still in daily use by Buddhists is the Po Nagar Cham Tower in Nha Trang. The temples of My Son were the most important temples of the Champa Kingdom. Bricks were used to build the temples, without mortar, and sculptures of gods, priests, animals, and scenes of mythical battles and devotion adorned the walls. These temples were places of worship of Lord Vishnu.
