It does not appear on any Ordnance Survey mapping until the 1940 edition of the six-inch series, which is a striking gap for a stone that may have been placed in its position thousands of years ago. Standing stones of this kind are generally understood to date from the Bronze Age, though in most individual cases a precise date cannot be established without excavation. Their purposes remain genuinely uncertain, with theories ranging from burial markers to boundary indicators to astronomical alignments.

The stone itself is modest by the standards of the more celebrated Irish examples. Probably granite, it has a rectangular cross section measuring roughly 73 centimetres by 35 centimetres, and it sits oriented east to west on a slight natural prominence in the landscape. That orientation is not unusual among standing stones, and the elevation, however gentle, suggests whoever placed it chose the spot with some deliberate care. Whether the east-west axis held any particular significance for those who erected it is unknown, but the combination of elevated ground and a carefully shaped stone points to something more intentional than a cleared field boulder left where it fell.
