Angkor was the political and religious center of the Khmer Empire from 802-1432. Angkor Wat, “City which is a Temple,” was built by Suryavarman II (1113-50) as a dedication to the Hindu god Vishnu (Protector of Creation). It is the largest religious structure in the world, measuring 1,626,000 sq meters. The layout is based on a mandala (sacred design of the Hindu cosmos). Unusually among Khmer temples, Angkor Wat faces west and toward the setting sun, a symbol of death, which makes scholars surmise that it was not only a temple, but initially designed as a mausoleum for the king as well.
