Tissa Wewa, an artificial reservoir, was built by Devanampiya Tissa (3rd century BC) in order to increase the water supply to his capital city of Anuradhapura.[1] Only Panda Wewa (5th century BC) and Abhaya Wewa (5th-4th century BC) are older. The embankment of Tissa Wewa is 2miles long and 25feet high.
Among other uses, the reservoir supplied water to Tissa's Royal Gardens.[2] In later centuries, Tissa Wewa and the other lakes were enlarged and integrated into a regional network of irrigation canals.[3]
