It has probably been there long enough that whoever last rebuilt the wall simply worked around it, or through it, treating it as just another upright. But cut into the eastern face, roughly at chest height, is a small Latin cross, incised by hand into the stone's surface, measuring about 27 centimetres tall and 16 centimetres wide. The cross is rough rather than decorative, the kind of mark made with intention rather than craft.

Cross-slabs of this type are among the more modest survivals of early Christian activity in Ireland. A Latin cross, distinguished from the equal-armed Greek cross by its longer lower arm, was one of the simplest and most portable of religious symbols, and carving it into an existing standing stone was a way of Christianising a landscape that already had its own monumental vocabulary. The stone itself may well predate the cross; standing stones were erected across Ireland from the Neolithic through the Bronze Age, and early Christian communities frequently marked or adapted them rather than removing them. This particular example, incorporated into a field wall, represents a pattern common across rural Cork and Kerry, where ancient stones were repurposed over generations until their original context was almost entirely obscured.
