My Son Sanctuaryis a cluster of abandoned and partially ruined Hindu temples in central Vietnam, constructed between the 4th and the 14th century by the Kings of Champa, an Indianized kingdom of the Cham people.

The temples are dedicated to the worship of the god Shiva, known under various local names, the most important of which is Bhadreshvara.

My Son Sanctuary is located near the village of Duy Phú, in the administrative district of Duy Xuyên in Quảng Nam Province in Central Vietnam, 69 km southwest of Da Nang, and approximately 10 km from the historic Champa capital of Trà Kiệu.

The temples are in a valley roughly two kilometres wide that is surrounded by two mountain ranges.

From the 4th to the 14th century AD, the valley at My Son was a site of religious ceremony for kings of the ruling dynasties of Champa, as well as a burial place for Cham royalty and national heroes.

It was closely associated with the nearby Cham cities of Indrapura and Simhapura. At one time, the site encompassed over 70 temples as well as numerous stele bearing historically important inscriptions in Sanskrit and Cham.

My Son is perhaps the longest inhabited archaeological site in Indochina, but a large majority of its architecture was destroyed by US bombing during a single week of the Vietnam War.
