The inscription is engraved on three sides of a quadrangular pillar, which was discovered in or before 1905 at the site of the so-called Raja-māḷigāva (royal palace) in the Citadel of Poḷonnaruva. In 1912, Wickremasinghe reported that the pillar had been moved to the premises of the Archaeological Commissioner at Tōpa-väva. The inscription consists of 118 lines in the Sinhalese alphabet of the early eleventh century A.D. It is dated to the eighth year of the reign of king Siri San̆g-bo and records the granting of immunities to a village called Kiṇigama, belonging to Kuḷu-Tisa-rad-maha-vehera of the Mahāvihāra Nikāya, situated in the Eastern Quarter. Wickremasinghe suggests that the biruda Siri San̆g-bo refers in this instance to Mahinda IV. The first three lines of the inscription are almost word-for-word identical with the two slab inscriptions of Mahinda IV at Jētavanārāma (IN03061 and IN03062).
