Angkor Wat is a temple complex at Angkor, Cambodia, built for the king Suryavarman II in the early 12th century as his state temple and 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. It is the world's largest religious building. (wikipedia)
