Wikipedia's[3] Angkor Wat article states construction "commenced in 1122 CE and was completed in 1150 CE," a period-based estimate rather than a single confirmed day, consistent with other sources citing the reign of Suryavarman II (1113-1150).Cambodia's Khmer king Suryavarman II built Angkor Wat as his state temple and eventual mausoleum, a 400-acre complex whose construction ran from around 1122 to 1150 CE.
