At Glenaglogh in County Cork, a standing stone that once rose from a south-east-facing pasture slope has since been removed, leaving behind little more than a footnote and a coordinate on a map. Standing stones are among the most enigmatic survivors of prehistoric Ireland, single upright slabs whose original purposes, whether territorial markers, ritual focal points, or memorials, remain a matter of ongoing debate. This one, modest by any measure, is now gone entirely.

The stone was recorded in 1939 by P. J. Hartnett, who noted it stood approximately three feet high. That record is almost all that survives. Notably, the stone does not appear on the Ordnance Survey six-inch map of 1842, which is a detailed and generally reliable document of the Irish landscape at that time. Its absence from that survey raises a small puzzle: the stone may have been overlooked by the surveyors, or it may have been partially buried or otherwise inconspicuous at the time the mapmakers passed through. Either way, by the time Hartnett encountered it nearly a century later, it was present and recorded. At some point after that, it was removed, its fate and current whereabouts unrecorded.
