The Terrace of the Leper King is an impressively large terrace, named after the Statue of the Leper King that sits on the top. It was built, like the nearby Elephant Terrace, by Jayavarman VII and later added to by Jayavarman VIII, who extended the terrace with a new surrounding wall, the old carvings were left preserved buried in earth behind the new wall. Since then the inner wall's carvings have been excavated and you can walk through a passageway between the old and new walls to view these hidden older carvings.
