From Wikipedia
Angkor, also known as Yasodharapura, was the capital city of the Khmer Empire, located in present-day Cambodia. The empire flourished from approximately the 9th to the 15th centuries. The site of Angkor has a variety of religious temples, libraries, moats, and other buildings. These other buildings could have been used by officials to the grand palace housing the Khmer king. Those constructed outside the main complex were not made of stone. One of the more visited places in Angkor is Angkor Wat, a temple complex that is one of Cambodia's tourist attractions.
