The Terrace of the Leper King is located in the Royal Square of Angkor Thom. The terrace was constructed in the Bayon style and features a statue of the Hindu god Yama. In Hindu mythology, Yama was the god of Death. The statue is appropriately named the "Leper King" because it was found in a very miserable condition, discolored, with moss growing from the stone. In essence, it looked very much like a man with leprosy.

Preah Pithu consists of five small temples. The temples are situated in a quiet place, a little further from the main touristic ruins.
