Angkor Thom
The fortified city of Angkor Thom (Great Angkor, or Great City), is on an epic scale, some 10 sq km in size. It was built by Angkor's greatest king, Jayavarman VII (r 1181-1219), who came to power following the disastrous sacking of the previous Khmer capital by the Chams. At its height, it may have supported a population of one million people in the surrounding region.
