The Cambodian ruins of Angkor, the capital of the Khmer civilization, consists of 72 major temples and other buildings from the 9th to 15th Centuries in an area about 15 miles across. The dense forest around the ruins shows how the city was lost for centuries until a French explorer rediscovered Angkor in 1860.

The southernmost temple is Angkor Wat, the largest religious structure in the world, a giant temple surrounded by a 570 ft wide moat. The west-facing temple comprises of three levels with the uppermost level originally being open to only the priests and king.
