Preah Ko is one of the four temples which make up the Roluos Group, the other three being Bakong, Lolei, and Prasat Prei Monti. It’s one of the oldest temples built during the Khmer empire and predates Angkor Wat by a few hundred years. The temple was built under the Khmer King Indravarman I in 879 to honor members of the king's family, whom it places in relation to the Hindu deity Shiva.
