A couple of interesting pictures from Google maps that you guys may like. First, this is the main temple Angkor Wat at the complex of temples named after this main one. Check out the scale: that moat is 200m wide and nearly 1km long. And it was dug by hand in the twelfth century. Also, note that it is facing perfectly west. This is uncommon for Buddhists as their temples always face east. Angkor Wat only became Buddhist recently in its history, though. It was constructed by a Hindu king.
To show you how badly deforested Cambodia is, check out the same place but zoomed out about four levels. The temples are in a preserve but all the land around them is free game. See the difference?
