A ringfort, the type of circular enclosed settlement that was the standard unit of rural habitation in early medieval Ireland, occupied a natural knoll here until around 1900, when local tradition holds it was levelled. What the site lost at that point was not merely an earthwork but a structure old enough to have been carefully recorded by Ordnance Survey mappers as far back as 1842.

The earliest OS six-inch map of 1842 shows the fort as a hachured arc running from south to north-west, the conventional cartographic shorthand for an earthen bank. The same feature appears again on the 1903 revision, still readable on a knoll sitting within the 200-foot contour line, a detail also visible on the 1939 edition. That the contour is noted across three separate map surveys suggests the natural topography, at least, has remained consistent, even as the archaeology above it disappeared. The levelling itself, dated loosely to around 1900 by local information, was a common enough fate for ringforts at that period, when agricultural improvement and building work frequently won out over earthworks that had survived for perhaps a thousand years.
