At Clashaganniv in County Cork, a gentle south-facing slope of pastureland holds nothing visible whatsoever, and yet it appears in formal archaeological documentation on the basis of local information suggesting a standing stone once stood here. The qualification is worth noting: not a confirmed monument, but a possible one, passed down through local knowledge and committed to the record despite the absence of any physical trace.

Standing stones are among the most common prehistoric monument types in Ireland, raised individually or in alignment from the Neolithic period onward, though many were likely erected during the Bronze Age. Their original purposes remain a matter of debate among archaeologists, with theories ranging from territorial markers to ceremonial functions to aids in astronomical observation. The stone at Clashaganniv, if it ever stood, left no such clues behind. By the time the site was assessed for the Archaeological Inventory of County Cork, Volume 5, published by the Stationery Office in 2009, there was no visible trace remaining at the location. Whether the stone was removed, buried, incorporated into a field boundary, or whether the local tradition referred to something that was already long gone before living memory, the record does not say.
