At Lisquillibeen in County Tipperary, the historical record points to a large circular enclosure, the kind of feature that typically marks an early medieval settlement or farmstead, ringfort-like in character, demarcating a domestic or agricultural space within a roughly circular bank or ditch. On the first edition Ordnance Survey six-inch map, produced in the mid-nineteenth century, the enclosure is clearly indicated. It looks, on paper, like a significant site. The ground, however, tells a different story.

By the time the revised Ordnance Survey edition appeared in 1903, something had changed in how the area was being read cartographically. The hachures marked on that later map, the small lines used by surveyors to indicate slope and relief, do not represent earthworks at all. They correspond to the natural cliff face of a quarry cutting into an area of rock outcrop. Quarrying was widespread across rural Ireland during the nineteenth century, used to extract stone for road-building, field walls, and construction, and it was not unusual for such activity to alter or entirely erase earlier landscape features. A field inspection carried out in 1995 confirmed what the later map had begun to suggest: there is no visible trace above ground of the large enclosure shown on the first edition. Whatever was once there, if anything physical ever was, has either been quarried away or was perhaps misread in the original survey.
