The 1926 revision of the OS six-inch map carried a small, roughly circular hachured marking at this spot, the kind of cartographic shorthand that can suggest an earthwork, a ring feature, or some structure of older provenance. When the site was inspected in 1984, the reality was more modest: a disused gravel pit, defined simply by the depression it left behind.

Gravel pits of this kind were commonplace across rural Ireland in the nineteenth and early twentieth centuries, dug to supply local road maintenance and farm trackways with loose surfacing material. They rarely warranted much attention, and once exhausted they were typically left to grass over, becoming minor dips in the landscape that only a close reading of a map might prompt someone to investigate. This one is considered probably of nineteenth or twentieth century date, placing it firmly in the era of organised road-making that followed schemes such as the Board of Works improvements. What makes it mildly curious is less what it is than what it briefly appeared to be, a cartographic ambiguity that persisted for decades before a field visit resolved the question.
