Where it originally stood, and how it came to rest on the beach, is simply not known. That absence of provenance is itself part of what makes the object quietly arresting: a piece of early Christian stonework with a clear purpose and careful decoration, yet entirely severed from any identifiable site or community.

The slab is modest in scale, just 0.56 metres long and between 0.15 and 0.19 metres wide, but its carving is deliberate and considered. One face bears a linear ringed Latin cross, the kind of early medieval design in which a ring intersects the arms of the cross. Here the ring is penannular, meaning it is not fully closed; the terminals curve outward rather than meeting, leaving the circle almost but not quite complete. In each of the four quadrants formed by the cross arms there is a small incised circle, though the one at the top right has suffered considerable weathering. Along either side of the cross stem, two short lines form a V-shape pointing outward toward the edges of the stone. The combination of the penannular ring and the V-shaped stem details is unusual, and the design was described in detail by E. Shee Twohig in a 1992 publication that remains the principal account of the piece. Cross-slabs of this general type are associated with early Christian practice in Ireland, often marking graves or enclosing sacred space, though without a known original location this one resists easy interpretation.
