You'll be glad to hear that we're at our last temple, Preah Khan. This was a large monastery, and housed 100,000 people in its heyday, and is also one of the unrestored temples. It's one of my favorites, largely because there were lots of fragments that you could mentally piece together to see how the site originally looked, and the whole thing looks so fragile. While it survived for centuries in the jungle, it will be interesting to see how these ruins hold up under the strains of mass tourism.
