Preat Kahn/ Preah Kahn (I have seen both spellings) It is a 12th century temple built by King Jayavarman VII on the site where he defeated the Cham (indigenous groups that occupied what is now coastal south Vietnam) invaders.
This temple had so much beautiful detail.
I thought it might be Tonle Sap, the remarkable body of water that encouraged civilization in this area. Tonle Sap is the largest fresh water lake in Southeast Asia and increases by over three times in size, taking in water from the Mekong, in the rainy season. It provides over half the fish consumed in Cambodia. I wanted to see this lake and I thought I might be looking at it in dry season, but no, this appears to be called simply Preah Kahn lake. It was nice, shallow with clear water for watching little fish darting around.
Neak Paen was next. This temple is on a sort of island surrounded by four human-made ponds. It is believed to have been constructed for health or medical reasons and that the ponds symbolized the four elements of earth, water, fire, and wind.
Visitors cannot walk on the stone path to the temple, so we viewed this temple at a bit of a distance. If you look close, you can see the stone horse statue in one of the ponds.
