This is Angkor Wat - the pride of Khmer culture and civilization. It was built between 1113 and 1150 and is a site to behold. It is the world's largest religious monument and is a depiction of the Hindu Universe culminating in the 5 peaks of Mount Meru (the 5 towers that you see in the center). Unlike the other ancient wonders of the world, Angkor Wat is not colossal in size, but it is an architectural masterpiece in fine proportion and extremely rich in detail containing about 600m of bas-relief and nearly 2000 apsaras (source: Ancient Angkor by Michael Freeman and Claude Jacques).
I made two versions of this photograph. This one in sepia and the other one in full colors.
Definitely better viewed large.
