Angkor Wat, the most famous tourist attraction in Cambodia, was originally a Hindu temple dedicated to the god Vishnu, but it has since become a Buddhist temple. Therefore, there is a Buddha Day every week. On Buddha Day, the third level, the Divine Realm, is not accessible, so please keep this in mind when planning your visit. Before the 11th century, Angkor Wat was composed of five levels: 1st level: World of Serpents 2nd level: World of Birds 3rd level: World of Humans 4th level: World of Demons 5th level: World of Gods However, after the 11th century, it was changed to a three-level structure: 1st level: World of Creatures 2nd level: World of Humans 3rd level: Divine Realm
