Preah Khan (Temple of the Sacred Sword) was built in the late 12th century (1191) by Jayavarman VII and is located just north of Angkor Thom. The temple was built on the site of Jayavarman VII's victory over the invading Chams in 1191. It was the centre of a substantial organisation, with almost 100,000 officials and servants. It served as a Buddhist university at one time. The temple's primary deity is the boddhisatva Avalokiteshvara in the form of Jayavarman's father.
