One side bears a Latin cross with expanded terminals, the kind of decorative flourish common in early medieval Christian stonework. Running along one edge, cut deeply into the stone, is an ogham inscription, the ancient Irish script that uses a series of notches and strokes along a central line to represent letters. The combination is unusual: ogham belongs primarily to an earlier, pre-Christian or transitionally Christian tradition, and finding it paired so deliberately with a confident Latin cross suggests a moment of cultural overlap, someone working at the seam between two worlds.

The stone was found in the 1940s somewhere near Kilbrittain, a coastal village in west Cork, though its precise original location has never been established. Its current dimensions, 0.56 metres tall, 0.28 metres wide, and 0.2 metres deep, tell only part of the story: damage to the lower portion of the block suggests it was once part of a considerably larger pillar stone, now lost or unrecovered. The ogham text along its edge has been read as TE-CORMAQ, likely a personal name in the genitive case, a form typical of early Irish memorial inscriptions that would translate roughly as "of Cormac". Whether the cross and the inscription were carved at the same time, or whether one was added to an existing stone, is not recorded.
