These are pictures of the Ta Prohm Temple in Cambodia. It was built about eight to nine-hundred years ago originally as a Buddhist monastery. Unlike most of the large Kmer temples this one was decided to leave relatively unrestored and to not get rid of the vegetation. As you can see this temple has really merged with the jungle over the years and the people in charge want to keep it that way.
Now here's some more pictures of this bad ass temple.
