Angkor what? Though the name may not be familiar to you, you will most likely recognize Angkor Wat. Built between 1113 and 1150 in northwest Cambodia, Angkor Wat was a temple complex originally dedicated to the Hindu god Vishnu, but converted to a Buddhist temple by the end of that century. When it was officially designated a World Heritage Site by the United Nations Educational, Scientific and Cultural Organization (UNESCO) in 1992, tourism to Angkor Wat had just over 7,000 visitors a year. It has since skyrocketed to more than two and a half million visitors each year.
