A baray () is an artificial body of water which is a common element of the architectural style of the Khmer Empire of Southeast Asia. The largest are the East Baray and West Baray in the Angkor area, each rectangular in shape, oriented east-west and measuring roughly five by one and a half miles. Historians are divided on the meaning and functions of barays. Some believe that they were primarily spiritual in purpose, symbolizing the Sea of Creation surrounding Mount Meru, font of the Hindu cosmos. Others have theorized that they held water for irrigation of fields. It is possible that the function was a combination of these explanations, or others.
