The Terrace of the Leper King (or Leper King Terrace) (Khmer: ព្រះលានស្តេចគម្លង់, Preah Lean Sdach Kumlung) 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 an 8th-century sculpture discovered at the site; . A datable inscription of the 14th-15th century identifies it with Dharmaraja, the "ruler of the order", another name of Yama, the Indic god of death.
The statue was called the "Leper King" because discolouration and moss growing on it was reminiscent of a person with leprosy, and also because of a Cambodian legend of an Angkorian king Yasovarman I who had leprosy.[1] The name that the Cambodians know him by, however, is Dharmaraja, as this is what was etched at the bottom of the original statue.[citation needed]
The U-shaped structure is thought by some[who?] to have been used as a royal cremation site.
