Translated as 'Great City', Angkor Thom was the last and
longest-serving capital of the Khmer Empire. The now abandoned city
covers an area of 3.5 square miles (9 square kilometres) and was
established by King Jayavarman VII as part of his grand and
ambitious building programme. At the centre of Angkor Thom is King
Jayavarman's state temple, Bayon, while within the city are the
remains of an earlier Khmer capital, Yasodharapa, which the newer
city overlapped, as well as buildings and temples established by
successors to King Jayavarman. The impressive city was thought to
have been home to as many as one million people at its peak, making
it part of the largest pre-industrial settlement in the world.
