So what to do in Siem Reap? Visit the Angkor ruins just north of the city!
Angkor was a great Khmer kingdom that built massive stone religious temples in the 10th through the 13th centuries. The most famous of all ruins is Angkor Wat, but there are loads of other ruins there too.
The Angkor ruins were "re-discovered" by the French late in the 19th century in a state of ruin. The jungle had encroached on many of the structures, and actually, poor knowledge of how to built with stone, lead to the early collapse of many of the sites (the Khmer used the stone as if it were wood).
