A monastery in Rohana, built by Mahánága, ruler of Mahágáma and brother of Devánampiyatissa (Mhv.xxii.9). Ilanága restored it and bestowed land for its maintenance (Ibid.,xxxv.31; MT.469). A story is related of a monk of this vihára who cut down a nága tree near the monastery. The devatá living in the tree was annoyed, and announced to the Thera that the king who looked after him would die in seven days. The Thera mentioned this in the palace; seven days passed and, as nothing happened. The king had the Thera's hands and feet cut off (VibhA.407). Near the monastery was a village named Kelakacchagáma (c.l. Kálagacchagáma) (MA.ii.1025). Dappula gave the village of Kevattagambhíra to the vihára (Cv.x1v.58).
