For several years it held a place on formal registers of potentially significant archaeological sites, entered in both the 1991 Sites and Monuments Record and the 1996 Record of Monuments and Places on the strength of a feature spotted in an aerial photograph. That is not an unusual way to identify earthworks; from the air, natural landforms can carry shadows and shapes that resemble deliberate human construction, the kinds of banks, ditches, and enclosures left behind by early medieval settlement or earlier activity.

Closer inspection, however, told a different story. The knoll itself is natural, roughly oval in plan, measuring approximately forty metres on its longer axis and twenty-four metres across. What caught attention from the air was a roughly square, sunken area cut into the top of the knoll, defined on its western and south-western sides by inward-sloping scarps. Rather than ancient earthmoving, this appears to reflect comparatively recent disturbance: a modern shed has been built against the base of the knoll on its eastern side, part of the south-eastern face has been quarried away, and a field boundary runs across the southern edge. None of the relevant Ordnance Survey six-inch map editions, which are a standard reference point for identifying long-standing landscape features in Ireland, show anything here. The conclusion reached on site was that the feature carries no archaeological significance, a verdict that effectively closes the file on what was, for a time, a candidate monument.
