Angkor Wat is a Hindu-Buddhist complex in Cambodia. Located within the ancient Khmer capital city of Angkor, it was originally constructed in 1150 CE as a Hindu temple dedicated to the deity Vishnu. It was later gradually transformed into a Buddhist temple towards the end of the century. Hailed as the largest religious structure in the world, it is one of the best examples of Khmer architecture and a symbol of Cambodia, depicted as a part of the Cambodian national flag.
