Yasovarman I (889 - 910 A.D.)
After succeeding the throne in 889 A.D, Yasovarman I built a new Angkor capital called Yasodharapura, located not far away from Roluos on the vast plain of Siemreap and about eight kilometers north of the the Great Lake Tonle Sap. At the center of this capital was the Phnom Bakeng Hill on top of which a temple was built with its galleries branching out in four directions to represent the heavenly residence of Hindu gods with the central Mount Meru and the other four sacred peaks.
Yasovarman I built one of the largest reservoirs in the Angkor Kingdom known as East Baray or "Yasohodharataka", with a length of 7.5 kilometers, a width of 1.83 kilometer and approximate depth of 4-5 meters. The water capacity of East Baray was estimated at 55 million cubic meters, and this water was used to irrigate over 8,000 hectares of farmland.
