This one is remarkable for what it no longer does. A standing stone that once occupied a field at Aghavrin in mid Cork has been gone since around 1980, leaving no visible trace on the ground. It is, in the most literal sense, an absence with a documented history.

The stone's existence is known almost entirely through a single cartographic moment. It does not appear on the Ordnance Survey six-inch maps of 1842 or 1903, which is itself unusual, since those surveys were generally thorough in recording upright stones and other field monuments. Then, on the 1938 six-inch map, it is marked clearly as a single standing stone. Whether it was overlooked in the earlier surveys, erected in the intervening period, or simply missed by earlier cartographers is not recorded. What is known is that by approximately 1980 it had been removed, and nothing on the surface now marks where it stood. Standing stones of this kind are among the most common prehistoric monument types in Ireland, typically dating to the Bronze Age, though their precise function remains debated; some may have served as boundary markers, others as ceremonial or ritual focal points. Whatever purpose this one served, it did so quietly, without fanfare, and has now disappeared just as quietly.
