The Bayon was the last state temple to be built at Angkor. Built in the 13th Century it is the only one to be built primarily as a Mahayana Buddhist temple (although various local deities were also worshipped there).

It was the centrepiece of Jayavarman VII's building program, and the similarity of the faces on the temple's towers to other statues of the king have led many scholars to the conclusion that the faces are, at least in part, representations of Jayavarman VII.
