Nachchaduwa wewa: History
This tank is believed to be one of the sixteen large reservoirs built by King Mahasen (277 – 304). It is said that he built this tank to supply water to the city and to safeguard the city from floods. However the chronicle Mahavamsa have made a reference to this reservoir during the time of King Moggallana II (540 - 560).
