Angkor Wat (Khmer: អង្គរវត្ត, 'City/Capital of Temples') is a Vaishnava Hindu and Theravada Buddhist temple complex in Siem Reap, Cambodia, and the largest religious complex in the world. Located on a site measuring 162.6 hectares (1.6 km2; 401.8 acres) within the ancient capital of Angkor, it was constructed between 1113 and 1150 CE during the reign of the Khmer king Suryavarman II as a Hindu temple dedicated to Vishnu. From the late 13th century onward, the complex was gradually transformed into a Buddhist temple and has remained an active center of Buddhist worship for centuries.
