This is actually the very front of Angkor Wat, where the moat goes around it. You only really see the front gateway and just the main sprire in the background :)
Is that actually Angkor Wat, or one of the, like 40+ other temples? We spent a week there and only got to see maybe 7-8 of them. I don't recognize this shot, but Angkor itself is so big I'm sure it could be from another angle.
