Angkor is one of the capitals of the Khmer Empire. The temple was built in order to worship the god Vishnu. The architectural plans were based on the Dravidian Architechture and key features coming from the Jagati. The temple itself was a combination of a temple and a mountain because it was a huge temple. The temple is the most important archaeological site of Southeast Asia, extending over 400 square kilometers and consists of scores of temples, hydraulic structures, and communication routes.
