West Baray

The West Baray or Baray Teuk Thla is a baray, or reservoir, at Angkor, Cambodia, oriented east–west and located just west of the walled city Angkor Thom. Rectangular in shape and measuring approximately 7.8 by 2.1 kilometers, the West Baray is the largest baray at Angkor and one of the largest handcut water reservoirs on Earth, possessing a current maximum capacity of 12 to 14 billion gallons of water. Its waters are contained by tall earthen dikes measuring 11.9 meters in height. In the center of the baray is the West Mebon, a Hindu temple built on an artificial island.

Construction of the baray probably began in the 11th century during the reign of King Suryavarman I: 95 : 371  and was finished later under King Udayadityavarman II.
