For years it was officially catalogued as an enclosure in the Record of Monuments and Places, the national inventory of archaeological sites, suggesting something far more ancient and deliberate than the reality turned out to be.

A closer look at the cartographic record set things straight. The Ordnance Survey 1:2500 plan, surveyed between 1912 and 1916, labels the feature plainly as a Gravel Pit, a working hollow cut into the ridge for the extraction of glacial gravel, the kind of loose, water-sorted material deposited across the Irish landscape during the retreat of the last ice sheets. The reclassification from enclosure to quarry is a small but telling reminder of how easily a hollow in the ground can be misread across categories, particularly when the original industrial purpose has been softened by decades of overgrowth.
