Founded by Angkor's greatest king, Jayavarman VII (reigned 1181-1219), Angkor Thom is one of the must-visit city when travelling to Cambodia. Angkor Thom means "the great city" in Khmer, was built in a nearly perfect square, the sides of which run north to south and east to west. It was surrounded by square wall and protected by a 100m-wide moat. There are five entrances (gates) to the city, one for each cardinal point, and the victory gate leading to the Royal Palace area. The original royal palace at Angkor Thom, built in the 10th and 11th centuries, was probably built of wood and no longer stands. This 12th-century royal Buddhist city is especially famed for its grand Bayon Temple, Terrace of the Elephants, Terrace of the Leper King, Baphuon temple and Phimeanakas Temple. Visitors should set aside a half day to explore Angkor Thom in depth.
