On the 1932 edition of the Ordnance Survey six-inch map, the site appeared as a hachured area, meaning it was marked with short radiating lines used by surveyors to indicate broken or uneven ground. That notation, open to interpretation, sat unresolved for nearly half a century until someone went to look. When the site was inspected in 1980, the hachuring turned out to represent something straightforward and functional: a quarry, the kind of working extraction site that once supplied local stone for roads, walls, and buildings across the Irish countryside.
