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.
