The Terrace of the Leper King (or Leper King Terrace)   Preah Learn Sdech Kunlung) is located in the northwest corner of the Royal Square of Angkor Thom, Cambodia. It was built in the Bayon style under Jayavarman VII, though its modern name derives from a 15th century sculpture discovered at the site. The statue depicts the Hindu god Yama, the god of Death. He was called the Leper King because discoloration and moss growing on the original statue was reminiscent of a person with leprosy, and also because it fit in with a Cambodian legend of an Angkorian king who had leprosy. The name that the Cambodians know him by, however, is Dharmaraja,[1] as this is what was etched at the bottom of the original statue.The U-shaped structure is thought by some to have been used as a royal cremation site.

Close to the Terrace of the Elephants is another Jayavarman VII commissioned terrace, the unattractively named Terrace of the Leper King. The terrace was named after the statue of the Leper King that sits on top. However, why the statue is known as the 'Leper King' is less clear, some argue that when the statue was found its lichen-eaten condition gave it the appearance of leprosy, others have argued that it is a statue of an Angkorian king who in Khmer legend suffered from the disease. It is difficult to see for yourself as the Leper King statue sitting proudly on the Terrace today is a replica, the original resides in the National Museum in Phnom Penh. The Terrace is deeply carved with nagas, demons, and other mythological beings, and it is believed to have been used for royal cremations.
