That small contradiction is, in a way, the whole story. The site is now classified as a removed monument with no visible surface trace, meaning that what once marked this patch of mid-Cork landscape has been taken away so completely that there is nothing left to find.

What makes the stone's history particularly elusive is how briefly it appeared in the cartographic record. The Ordnance Survey mapped Ireland in exhaustive detail from the 1830s onwards, and the 1842 six-inch map of the area records no standing stone at Glenaglogh. The same is true of the 1904 revision. Standing stones are prehistoric monuments, typically single unshaped or roughly shaped upright stones whose original purpose remains debated, with theories ranging from territorial markers to ritual or astronomical functions. Whatever this one meant to the people who raised it, it had apparently vanished from local consciousness, or at least from official notice, by the nineteenth century. Then, in the 1938 Ordnance Survey revision, it appears, marked plainly as a single standing stone. Sometime after that, it was removed entirely.
