Preah Kor temple is located between Bakong and Lolei on the western side of the road to Bakong. The temple was built in 9th century by King Indravarman I62 ( AD 877-889), Dedicating to Shiva Brahmanism. It is also a funerary temple built for the King’s parents, maternal grandparents, and a previous king, Jayavarman II and his wife.
Originally square in plan and surrounded by three ramparts with gopuras, the complex seems small today because of the dilapidated state of the rampart. The outer rampart is 400 by 500 meters square with gopuras on the east and west sides. A small terrace which is largely destroyed precedes the laterite gopura at the east. Long halls or galleries parallel thee middle rampart, two each at the east and west, and one each at the northeast and southeast. There are galleries with a porch opening to east on the north and south sides of the walkway. An unusual, square, brick structure stands between the long hall and the gallery at the south. The brick rampart inside has two gopuras at the east and directly opposite on the west.
Three images of Shiva’s mount Nandi are at the east of central area. Although only portions of the bulls remain, their original position can be discerned facing to the temple. The central areas consists of brick towers set towards the east in two row on a low platform. The shrine of Preah Kor are built near ground level-a typical feature of Khmer temple that are dedicated to ancestors. The central towers are square in plan with a porch in each of the cardinal directions. Each of six towers of the central group was covered with elaborate stucco.
