On the 1946 revision of the Ordnance Survey six-inch map, it appears as a hachured feature, the small radiating lines that mapmakers traditionally used to suggest a depression or raised earthwork. To anyone studying the map, it might have looked like an ancient enclosure, a collapsed ringfort, or some other remnant of early settlement. When someone finally went to look in 1984, it turned out to be a disused quarry.

That gap between appearance and reality is the quiet interest here. The quarry post-dates 1700, which places it in a period when small local quarries were commonplace across rural Ireland, typically worked by hand to extract limestone or other stone for field walls, farm buildings, and road repair. Such workings were rarely documented in any formal sense; they were practical features of agricultural life, opened when needed and abandoned when the stone ran out or the need passed. What lingers is the feature itself, grassed over and settled into the landscape, legible on a mid-twentieth-century map as something that warranted marking, even if nobody at the time was entirely sure what it was.
