The slab, measuring roughly 85 by 55 centimetres, is only the lower portion of what was once a larger funerary monument, yet even in its truncated state it carries considerable detail. A calvary mount, the stepped base on which a cross traditionally stands, is still clearly visible, and within its curving form a skull and crossbones has been carved in false relief, meaning the motif is suggested by incised lines rather than cut proud of the surface. A marginal inscription runs along the edge, dated 1636, though the rest of the text survives only in fragments: traces of names or words that read in part as RODCES GENERO and ARCKI, too damaged to reconstruct with confidence.

The wall in which the slab is embedded belongs to a Church of Ireland building that replaced a much older structure. The medieval church of St. Nicholas of Myra stood on this site until around 1813, when it was demolished to make way for the new church. St. Nicholas of Myra, the fourth-century bishop whose later legend gave rise to the figure of Santa Claus, was also the patron saint of sailors, merchants, and children, and dedications to him are found across medieval Ireland. When the old church came down, the graveslab, already nearly two centuries old by that point, was not discarded but built into the replacement structure, preserved almost by accident in the fabric of the wall. The 1636 date places its carving firmly in the early seventeenth century, a period when skull-and-crossbones imagery was common on Irish funerary monuments as a reminder of mortality, a visual shorthand familiar from graveyards across the country.
