These are cup-marks, shallow circular depressions ground or pecked into stone, typically between four and five centimetres in diameter here, and among the most enigmatic of prehistoric markings. Nobody knows with certainty what they meant to the people who made them. Ritual, territorial, astronomical, and purely decorative explanations have all been proposed over the decades, and none has settled the question.

The slab itself measures roughly 1.4 metres by 1.1 metre and sits about fifty metres to the north-west of a ringfort, the kind of enclosed circular settlement built across Ireland from the Iron Age through to the early medieval period. That proximity is unlikely to be accidental, though whether the stone was already ancient when the ringfort was constructed, or whether both features belong to broadly the same period of activity, is not recorded. Adding further texture to the immediate landscape, a standing stone lies only about five and a half metres to the east of the cup-marked slab, suggesting this corner of mid Cork was, at some point in prehistory or early history, a place of deliberate and considered arrangement rather than scattered, unrelated monuments.
