It measures just over two metres in length and sits inside 'Teampul na bhFear nGonta', a name that translates roughly as the Church of the Wounded Men, one of several early ecclesiastical structures within the 'Saint's graveyard' on Inis Cealtra, the island also known as Holy Island.

Inis Cealtra was a significant monastic site, associated with Saint Caimin and active from the early medieval period. The graveslab is one of four recumbent slabs, that is, flat memorial stones laid horizontally over or near burials, found on the floor of this particular church. When the archaeologist R.A.S. Macalister surveyed and drew up a plan of the graveyard sometime around 1916 to 1917, this slab was recorded in his drawings but left without a number, a small omission that means it has sat at the edge of the formal record ever since. Whether that reflects uncertainty about its date, its condition, or simply the practicalities of fieldwork is not clear, but the result is a stone that has been seen and noted without quite being named.
