Nokor Wat

Nokor Wat is an Angkorian temple dating from the 11th century, containing a standard assortment of Angkor architecture. Some of the mausoleums are open to tourists and contain piles of bones and skulls from the Khmer Rouge's genocidal reign. Inside one of the buildings is a very elaborate series of wall paintings, depicting torture and executions (of a religious nature), as well as scenes of heaven and the afterlife. This is not always an accessible building, as a Monk has to unlock it for you to enter.
