It would be easy to walk past without registering its significance. The slab tapers slightly from top to base, measuring just over a metre in length, and carries no inscription, no name, no date. Whoever it once commemorated is entirely unknown.

What the slab does preserve, in the shallow language of groove-work, is a carefully composed cross design. Three parallel grooves form what is described as a double outline cross-stem, the kind of decorative device found on early medieval graveslabs across Ireland, where the cross form was incised into the stone rather than raised in relief. The outer grooves extend from a rectangular panel near the top of the slab, while the central groove begins at the top of that same panel and bisects it, dividing it into two halves, each containing a single short incised line. A grooved border, roughly a quarter of a metre wide, runs close to the edge of the slab, though on the left-hand side only traces of it now survive. The precise date of the slab is not established, but this kind of incised cross decoration is broadly associated with early Christian burial practice in Ireland. A second slab of comparable type lies approximately four and a half metres to the north, within the same chancel, suggesting that this corner of the church once held burials of some deliberate arrangement or communal significance.
