The inscription is engraved on a fragment of a stone slab found in the Tōpaväva village. The fragment originally formed part of a flagstone in the rectangular bath on the promontory at Tōpaväva. Numerous baths were discovered on the promontory in 1901. The other fragments of the flagstone are missing but Wickremasinghe was able to reconstruct the slab’s inscription after recognising that it was the same as the Rankot-dāgaba pillar inscription (IN03087), except for the concluding sentence which states the purpose for which the cistern was used by king Niśśaṅka-Malla. This king reigned from 1187 to 1196 A.D. No specific date is given in the inscription but, as Wickremasinghe notes, the text must have been composed after the fourth year of Niśśaṅka-Malla’s reign because it refers to the king’s visit to Anurādhapura, which took place in his fourth regnal year, and to his later tours of inspection.
