On the 1933 edition of the Ordnance Survey six-inch map, a hachured marking, the cartographic shorthand for a depression or earthwork, sits quietly on the sheet, inviting the kind of speculation that old maps reliably produce. It might have been a ringfort, a quarry of some antiquity, or some other feature worth investigating. When someone finally went to look in 1983, the answer turned out to be considerably more ordinary: a disused gravel pit, its edges long since softened by vegetation into an overgrown hollow.

The gap of fifty years between the map and the inspection is itself quietly telling. The six-inch Ordnance Survey series, produced across Ireland from the nineteenth century onwards, recorded the landscape with remarkable detail, but a hachured symbol on its own carries no label, no explanation. Whatever the original surveyor saw or assumed, the feature passed into the cartographic record without clarification. Because the gravel pit dates to after AD 1700, it falls outside the scope of formal archaeological classification, which in Ireland generally concerns itself with earlier remains. That boundary is a practical one, and it means this particular hollow occupies an administrative gap, documented but uncategorised, neither ancient monument nor modern infrastructure.
