Angkor Thom and Bayon

Angkor Thom was the political capital of the King Jayavarman VII, greatest of the Angkor builders. In its time this was the largest city in the world with over a million inhabitants.

At over 9 square km and completely enclosed by a moat and high laterite wall the city contains at its centre the complex of Bayon. Most visitors will approach the city from the South gate which is fascinating in its own right. Bayon is dominated by the 200 enormous stone faces of King Jayavarman VII on the 54 towers. The bas-relief carvings of Bayon provide a unique insight into everyday Angkor period life.
