Prasat Don Kau

Prasat Don Kau, also called Prasat Kantop, is an old Khmer sanctuary in the country south of the Dangrek Mountains. It stood near an ancient route linking Angkor's eastern road network with the lands toward Vat Phou. The site includes three brick shrines and inscriptions in Khmer and Sanskrit, among them a record dated to the eleventh century. These remains mark the religious and administrative presence of the Angkorian world beyond its capital.

The later city of Preah Vihear lies here.
