For a decade it was recorded as a ringfort, the circular earthwork enclosure so common across the Irish landscape, built largely in the early medieval period as a defended farmstead. Then, ten years later, it was quietly reclassified as a quarry.

The shift in designation tells a small story about how archaeological knowledge accumulates and corrects itself. In 1988, the Sites and Monuments Record listed the feature as a ringfort. By 1998, when the Record of Monuments and Places was compiled, the assessment had changed, and the entry was recast as a quarry. The conclusion reached was that the evidence was not sufficient to accept the site as the location of an archaeological monument at all. What had once been tentatively entered into the national record as a prehistoric or early medieval enclosure was, on closer examination, more likely the product of relatively modern stone extraction. Quarrying can leave circular or semi-circular depressions in the ground that, from a distance or on early maps, bear a passing resemblance to a ringfort's profile. It is a confusion that has occurred elsewhere in Ireland, where the physical trace of human industry gets misread across time.
