Dighavapi
Dighavapi ( Pali, "long reservoir") is a Buddhist sacred shrine and an archaeological site in the Ampara District of Sri Lanka, boasting of historical records dating back to the 3rd century BCE. Water reservoirs, called "tanks", were an important feature of the hydraulic civilization of ancient Lanka, and temples and cities were built around them. The importance of Dighavapi is connected with legends about visits to this site by the Buddha himself, and many allusions to Dighavapi in the ancient chronicles as well as in the Pali literature. It has also played a role in the political history of the region. In more recent (medieval) times, the Sinhalese kings have settled Moor and Dutch settlers in the neighbouring areas.
