For a country whose landscape has been measured, charted, and catalogued with considerable thoroughness, a standing stone that slipped through that net is an oddity worth noting. Standing stones are among the oldest surviving human constructions in Ireland, raised during the Bronze Age or earlier as markers, memorials, or boundary indicators, their precise purposes still debated. This one, in the townland of Ballynagallagh, simply stands where it has always stood, unacknowledged by the cartographers.

The stone was recorded by O'Kelly in 1944, who described it as a limestone pillar approximately 1.5 metres high, with a base measuring roughly 0.53 metres by 0.4 metres. Those are modest dimensions, nothing monumental, but sufficient to confirm that this is a deliberately placed upright stone rather than a natural outcrop. The name Ballynagallagh is itself suggestive; the Irish "gallach" relates to standing stones, meaning the place-name may carry the memory of the monument within it, even if the maps do not. Beyond O'Kelly's brief description, the documentary record is thin.

Finding a stone that was omitted from the Ordnance Survey requires a certain patience and some local knowledge. The townland of Ballynagallagh lies in County Limerick, and anyone hoping to locate the stone would do well to consult the National Monuments Service records as a starting point, cross-referencing O'Kelly's 1944 account. The stone's limestone composition means it weathers differently from the granite or sandstone pillars more common elsewhere in Ireland, and closer inspection of its surface texture may be more rewarding than its modest height first suggests. Visiting in late autumn or winter, when vegetation is lower, gives the best chance of actually spotting a small standing stone in open ground.
