On the north-eastern edge of the Monks' Graveyard sits the remnant of a stone cross, barely thirty centimetres tall, that has lost both its head and one of its arms to time. What survives is a sliver of worked stone, just five centimetres thick, with a shallow hollow cut into the lower angle of the remaining arm and faint traces of a linear Latin cross still visible on its western face.

The cross was recorded in 1996 by archaeologists A. O'Sullivan and J. Sheehan as part of a comprehensive survey of the Iveragh Peninsula. At that point the damage was already done and undatable, but the object itself belongs to a tradition of simple incised stone crosses that were common markers in early Irish monastic burial grounds. A linear Latin cross, where the upright is longer than the crossbar and the design is carved in plain recessed lines rather than sculpted in relief, is among the most austere forms such monuments take. On Skellig Michael, a UNESCO World Heritage Site whose beehive cells and oratories cling to sheer cliff faces some twelve kilometres off the Kerry coast, even a fragment like this sits within one of the densest concentrations of early Christian stonework in Ireland. The graveyard it marks is not a romantic abstraction; it is where the monks who lived on this rock were buried, in a place where the wind rarely stops and the sea is audible from every direction.
