My Son is a group of temple-towers of Cham people. With its great value, in December 1999, the complex of My Son Cham Towers has been recognised as a World Heritage Site by UNESCO.

Various researches by archaeologists and architects have revealed that at the beginning, there was only one small wooden temple built by King Bhadresvara I in late 4th century. In the 7th century, King Sambhuvarman had it rebuilt, using more durable materials From then on, successive Cham kings, when enthroned, had their temple-towers constructed as offerings to their gods. During seven centuries (7th to 14th century), such temple-towers mushroomed in My Son, turning this land into a cultural, and religious center of the Cham Kingdom.

My Son was a complex of constructions, including different temple-towers and stela in various architectural styles. French researchers listed some 70 temple-towers there. However, time and war together have taken their toll on these relics. Now, only 20 temple-towers remain almost intact. The rest have been reduced to ruins. These vestiges are valuable treasures of information for studying the development of Cham culture. During its seven centuries of development, Cham arts produced many works equal to masterpieces of the world. Though less impossing than the Angkor in Cambodia and less diversified than the Pagan site in Myanma, My Son is unique of its kind in Southeast Asia.
