Angkor Thom was the last and most enduring capital city of the Khmer empire. It was established in the late twelfth century by King Jayavarman VII. The south gate of Angkor Thom is the best preserved. It is approached from outside via a causeway that extends about fifty meters across a moat. On each side of the causeway are railings fashioned with 54 stone figures engaged in the performance of a famous Hindu story.
