Angkor Wat is a Hindu temple complex at Angkor, Cambodia, built for the king Suryavarman II in the early 12th century as his state temple and part of his capital city. As the best-preserved temple at the site, it is the only one to have remained a significant religious centre since its foundation — first Hindu, dedicated to the god Vishnu, then Buddhist. The temple is at the top of the high classical style of Khmer architecture.
