Near Grenagh in mid Cork, there was once a standing stone, one of the many thousands of upright monoliths that punctuate the Irish landscape, often of prehistoric date and frequently positioned near other ancient features. This particular stone was recorded as standing just south of a ringfort, the kind of circular earthwork enclosure used as a farmstead during the early medieval period, roughly the fifth to twelfth centuries. At some point between that recording and now, the stone was removed entirely. There is no visible trace of it at ground level.

What makes this absence worth noting is the precision with which the stone's existence was captured. The sole cartographic evidence for it comes from the Ordnance Survey six-inch map of 1938, a series that remains one of the most detailed mid-twentieth-century records of the Irish countryside, including features that were already old or fading when the surveyors passed through. The stone's proximity to the ringfort may not have been coincidental. Standing stones and ringforts occasionally occur together in the landscape, and while the relationship between them is rarely straightforward, the pairing suggests the area around Grenagh was a place of some significance across different periods. Without the stone, that spatial relationship can now only be inferred from a map that is itself nearly ninety years old.
