Ruwanweliseya Stupa (Ruwanveli Seya Stupa), the foremost of the supremely glorious ancient living monuments of Sinhalese Buddhist Heritage at the city of Anuradhapura (a UNESCO World Heritage Site-Culture) was built by King Dutugamunu (161-137 BC), the Hero of the Nation, who hailed from Ruhuna, which was destined to give birth to most of the glorious heroes of the island nation of Sri Lanka from the ancient era to the modern day. Ruwanweliseya Stupa (Ruwanveli Seya Stupa) also called Maha Stupa (Sinhala: the great dagoba) or Ratnapali Stupa or Swarnamali stupa has been the most adored, most venerated among the great ancient stupas (dagobas) of Sri Lanka. Anuradhapura is replete with the ancient cultural monuments located in between the River Malwatu Oya and two great ancient man-made irrigation reservoirs called Tissa Wewa and Abhaya Wewa (Basawakkulama Wewa). These two ancient irrigation reservoirs, together with ancient Nuwara Wewa reservoir on the eastern flank of the River Malwatu Oya, extend the lifeline to the agricultural district of Anuradhapura.
