A monastery in Ceylon, built by Amandagāmanī Abhaya (Mhv.xxxv.4; but see Cv.c.238, where Dutthagāmanī is stated to have built it). It was in Ambatthakolalena, where silver was discovered for use in the construction of the Mahā Thūpa (Mhv. Trs.188, n.1). Kittisirirājasīha (Cv.xcix.41) visited the vihāra and paid it great honour and gave it to a sāmanera called Siddhattha (Cv.c.238). The vihāra is now called Ridī vihāra and is near the modern Kurunegala.
