Inis Cumhscraigh, a pre-Norman monastery, slightly north of a Cistercian foundation (Hamlin 1977, 85), appears to have functioned into the 12thc. The Cistercian abbey was founded in the 1180s by John de Courcey as a daughter house of Furness in Cumbria.
The fragment is now stored at the DOENI (Department of the Environment Northern Ireland) stone store at Castlewellan.
