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. The Mahavamsa, an ancient chronicle written in the 5th century, and the Dipavamsa of an earlier date, contain a mixture of legend and historical facts. These chronicles state that the Buddha himself visited the village, and on the spot where he sat in meditation a cetiya was later erected - Wiki
