It measures 0.6 metres high, 0.5 metres wide, and roughly 0.1 metres thick, which makes it a modest thing physically, but its placement is deliberate. Stones like this were set at the thresholds or within the precincts of early Irish religious sites, functioning as markers of sacred ground rather than purely decorative objects. The act of carving a cross into stone was itself a form of consecration, a way of fixing a claim on a place.

The slab sits alongside what appears to be cairn-like material, suggesting that earlier or accumulated structure underlies what is visible today. Recorded by Cuppage in 1986, the site also has a modern cross erected on the immediate eastern side of the oratory, which creates a slight layering effect: the ancient incised stone at the entrance, the later addition nearby. That juxtaposition, old carving and newer monument occupying the same small precinct, is common at sites of continuous local veneration, where communities have returned across centuries without necessarily distinguishing between periods.
