It is not especially large, measuring roughly 80 centimetres across and 33 centimetres thick, and there is nothing to announce it or explain it. It simply stands, as it has stood for millennia, with a wide view opening southward over Bantry Bay and the town below.

Standing stones of this kind are scattered across the Irish landscape in considerable numbers, though their precise purposes remain genuinely uncertain. They are generally understood to date from the Bronze Age, and have been interpreted variously as boundary markers, commemorative monuments, or components of now-vanished ritual landscapes. What distinguishes this particular example is its deliberate orientation, the ENE-WSW alignment suggesting it was positioned with some intention, possibly astronomical, possibly territorial. The location on Knocknaveagh reinforces that sense of deliberateness: the elevated position commands exactly the kind of broad, legible view over sea and settlement that recurs at prehistoric sites across the south-west of Ireland.
