Apsaras carved on the inner wall of the West entrance to Angkor Wat, Cambodia. There are 2,000 of these apsaras, celestial maidens who entertain the gods, in bas-relief at this temple. Angkor Wat is the world's largest religious monument and an architectural masterpiece, the apogee of classical Khmer style. Built between 1113 and 1150 by King Suryavarman II, it was both city and temple, the capital of the Empire and the State Temple dedicated to the god Vishnu. Surrounded by a broad moat, it covers 200 hectares (1.5 km by 1.3 km) and is a microcosm of the Hindu universe.
