Preah Khan temple is located nearby the Northgate of Angkor Thom city about 500 meters and just west of the Jayataka reservoir, massive temple in Cambodia, and was built in the late 12th century for King Jayavarman VII to dedicate his father. It was the centre of a substantial organization, with almost 100,000 officials and servants. The temple is flat in design, with a basic plan of successive rectangular galleries around a Buddhist sanctuary complicated by Hindu satellite temples and numerous later additions. Preah Khan temple has been left largely unrestored but it is a wonderful temple and you can also see the beautiful atmosphere of the south entrance.
