Bayon Temple looks a bit chaotic for me, judging from the view from the outside. On top is a photo I took in front of the temple. It is impressive nonetheless for the countless towers with carved Buddha faces. Our tour guide said there are around 200 but since a lot might have fell into ruin over the years, there is no actual count. Below are two close-up looks to two of the Buddha faces: one was courtesy of our tour guide and the other one is on a postcard.
