Built in the latter part of the 12th century by King Jayavarman VII, Bayon is one of the most widely recognised temples in Siem Reap because of the giant stone faces that adorn the towers of Bayon. There are 54 towers of four faces each, totaling 216 faces. There is still a debate as to who is being depicted in the faces. It could be Avalokiteshvara, Mahayana Buddhism's compassionate Bodhisattva, or perhaps a combination of King Jayavarman VII and Buddha.
