Cut into its surface are four cup-marks, shallow circular depressions each up to ten centimetres across, along with a larger oval hollow measuring roughly 36 centimetres in length and 27 centimetres wide, sunk about eight centimetres into the stone. That oval depression may be a bullaun, a term for a worked stone basin, often bowl-shaped, which appears at many early medieval Irish sites and is frequently associated with ritual or devotional use. Whether the cup-marks and the possible bullaun were made at the same time, or represent different periods of use layered onto the same convenient outcrop, is not recorded.

Cup-marked stones are found across Ireland and much of Atlantic Europe, and while their exact purpose remains genuinely unclear, they tend to cluster in landscapes already carrying other signs of early activity. Here, that pattern holds. Roughly 170 metres to the east lies a holy well, the kind of site that in Ireland often preserves a much older layer of local significance beneath its later Christian associations. The proximity of the two features, the marked outcrop on the slope and the well a short distance away, suggests this corner of West Cork was a place people returned to, and marked, over a long stretch of time.
