Most grave slabs of the period bear a simple Latin or foliate cross; this one has only three arms, with a broad shaft running the full length of the stone and terminating neatly at the lower border, while a curving band arcs between the two upper side arms and the top of the cross-head. Below that cross-head sit two broad horizontal bands, stacked one above the other, each tapering to a simple point, the lower one slightly shorter than the one above. The overall effect is geometrically deliberate, yet unlike the decorative vocabulary seen on comparable medieval Irish slabs.

The slab itself is rectangular limestone, measuring just over two metres in length, sixty-two centimetres wide, and about sixteen centimetres thick. A plain border runs around the edge without any chamfering, the term for the angled cutting-back of a stone's edge that was common on dressed medieval stonework. Within that border, on the upper left-hand side, there is a short Latin inscription in raised black-letter script, the angular lettering style widely used across medieval Europe, though here it has become illegible. The slab's identity has a small puzzle attached to it: it does not appear to be the same graveslab recorded at the same church by a researcher named Brennan, writing in the mid-nineteenth century around 1854 to 1855. Whether Brennan's slab has since been lost, buried, or removed is not clear, which raises the quiet possibility that at least two notable slabs once marked graves here.

The slab lies two metres north of the east end of the church's north wall, close enough to the ruined structure that the relationship between the two is immediately legible on the ground. The church itself is a roofless medieval ruin, and the slab sits in the open air beside it, which means weathering continues to work on what little remains of that border inscription.
