Known locally as Leac na Ré, it is almost perfectly square, just over a metre in both height and width, and its southern face carries carving of considerable delicacy. A Greek cross, its four arms each ending in a slightly expanded terminal, sits enclosed within a penannular circle, that is, a circle left deliberately incomplete. Where the circle opens, the ends curve downwards into spiral motifs, and from the base of the cross a stem descends through the gap itself, as though the design is threading its way out of its own frame.

The geometry here is not accidental. Early medieval Irish stone carvers working in the tradition of the sixth to ninth centuries developed an intricate vocabulary of crosses, circles, and spirals, often on slabs associated with burial grounds or monastic enclosures. The calluragh nearby, a term for an early burial ground often linked to unbaptised children or pre-Christian usage, places this slab within a landscape that was clearly significant over a long period. The carving was documented by J. Cuppage in the 1986 Corca Dhuibhne archaeological survey of the Dingle Peninsula, a landmark study of one of the most densely layered early Christian landscapes in Ireland. What makes the Leac na Ré slab particularly absorbing is the way the pendant stem passes through the opening in the penannular circle, a compositional choice that gives the design a sense of movement and intention rather than simple repetition of a standard motif.
