Shortly after defeating the Cham in 1178, Jayavarman VII became King of the Khmer Empire and launched a massive building campaign. His first project was Bayon located within an area now called Angkor Thom. It was initially a Buddhist temple but later became Hindu. This state temple was structured to resemble Mount Meru, the intersection of heaven and earth. The archeological gem is famous for its 216 giant stone faces on the 37 remaining towers. Originally, there were 49 prasats.
