Most of the temples in Angkor Wat are chambers within chambers, galleries and passageways leading from one courtyard to another. Temples like Preah Khan (where this shot was taken) for example, seem like a mass of doorways connected by courtyards, rather than the other way around.
This second one is from either Ta Prohm or Beng Melea: I can't remember which by now. There's a sense of mystery walking through these temples, and a little bit of awe. Preah Khan especially - it was getting dark as we walked through it, and the light was failing fast. There was the fear was getting lost in the temple and night falling, and being alone in a very, very eerie place.
