It is recorded, it has a classification, it occupies a precise location on a west-facing pastoral slope, and yet there is no visible surface trace of it whatsoever. That combination, a monument that is simultaneously documented and invisible, is its own kind of curiosity.

Standing stones are among the most enigmatic survivals of prehistoric Ireland. Erected singly or in loose groupings, usually during the Bronze Age though sometimes later, they served purposes that remain genuinely unclear, whether as territorial markers, ceremonial focal points, or memorials. Most have endured for millennia simply because a large upright stone is difficult to ignore and awkward to remove entirely. The one at Glan appears to have been removed, buried, or swallowed by the pasture above it, leaving only the record behind. The 1992 Archaeological Inventory of County Cork noted it with the terse observation that no visible surface trace remained, a phrase that carries a particular weight in field archaeology, signalling that something was once confirmed or credibly reported here but can no longer be seen.
