At Carrigmore in County Cork, a feature recorded as a quarry in the late twentieth century occupies a peculiar position in the historical record, present enough to be noted, absent enough to resist any firm interpretation.

The site appeared as a quarry in two successive surveys, the first in 1988 and again in 1998, but subsequent examination found the evidence too thin to confirm it as a genuine archaeological monument. That distinction matters more than it might seem. A working quarry is, by its nature, a place of removal rather than accumulation, and quarries in Ireland range from small, locally worked stone-pits serving a single farm to larger industrial extractions. Whether this particular feature at Carrigmore was ever actively worked, or whether the original classification was based on a surface reading of the landscape, remains unresolved. The record exists; the site, in any meaningful archaeological sense, does not quite.
