The reason for the site's name is the finding of "Leper King" statue. Terrace of Leper King was built by Jayavarman VII in late 12th century, just north of Terrace of Elephants.
The terrace was believed to be built as a representation of Buddhist's sacred Mount Meru which is the center of the universe. A large number of sculptures completely covered the 25-m long terrace, featuring Naga snakes, armed guardians, Garudas and female celestial beings.
The 'Leper King' Statue
On top of the terrace stands the Leper King which is believed to be a depiction of King Yasovarman I who had suffered from leprosy or God of Death - Yama. The statue is just a copy of the real statue which is now kept at s museum in Phnom Penh.
