Famous for its sunset views of Angkor Wat, the Tonlé Sap, and the Bayon, the ancient Hindu temple of Phnom  Bakheng surveys the surrounding plains from the top of a  220-ft (67-m) high hill. Built by King Yasovarman I, the Bakheng complex is one of the region’s first examples of Mount Meru-style temple architecture. The complex was once surrounded by 109 towers spread around its six tiers; however, most of them are now missing.
