This one is notable for what does not. A standing stone that once occupied a north-facing pasture slope at Kilmoney in County Cork was removed around 1965, leaving behind no visible trace, only a record of its former existence. Standing stones are among the most enigmatic monuments in the Irish landscape, single upright slabs erected during the Bronze Age or earlier, whose original purposes remain debated; they may have marked boundaries, burial sites, astronomical alignments, or simply significant points in a community's territory. Whatever its meaning, the Kilmoney stone is now gone, and the field where it stood holds no obvious sign that anything was ever there.

The earliest known reference to the stone comes from O'Leary, writing in 1919, which suggests it was still standing in the early twentieth century and had been noted as a feature of local archaeological interest. At some point in the mid-1960s it was removed, a fate that befell many such monuments across Ireland during a period of agricultural intensification, when large stones were increasingly seen as obstructions rather than antiquities. The north-facing slope setting, while unremarkable in itself, is the kind of quiet pastoral ground that could easily absorb the loss of a single upright stone without anyone beyond a handful of observers taking notice.
