That single word implies a monument considered significant enough to record, most likely a standing stone, one of the upright monoliths erected across Ireland from the Neolithic through the early medieval period, often as territorial markers, burial indicators, or ceremonial waypoints. Whatever stood here has since vanished entirely, leaving no visible trace above ground.

In its place, a limekiln now occupies the site. A limekiln is a stone-built furnace once used to burn limestone and produce quicklime for agricultural use, a common enough feature of the rural Irish landscape in the eighteenth and nineteenth centuries. Its construction here may well account for the disappearance of the earlier monument; stone was a practical resource, and standing stones were frequently dismantled and reused. When the site was investigated in more recent times, the landowner had no memory of any monument ever being there, which suggests the original feature had been gone long enough to pass out of local knowledge entirely. What the 1838 cartographers recorded, and what prompted them to name it, remains unclear. The word 'Stone' on that old map is now the only evidence that anything was ever there at all.
