That uncertainty is not a recent failing. When Matthew Stout conducted the Ikerrin Survey in 1984, the site was misidentified altogether, logged as a natural hillock rather than an archaeological feature. The confusion is understandable: circular enclosures, often the remains of early medieval ringforts or their predecessors, depend on their earthen banks and ditches for visibility, and once those are gone, so is any obvious sense that human hands shaped the ground.

The Ordnance Survey had no such trouble, at least initially. Both the first edition six-inch map of 1840 and the revised edition produced between 1901 and 1905 mark the site clearly as a small circular enclosure. That continuity across more than sixty years of mapping suggests the feature was legible on the ground at least into the early twentieth century. At some point between those surveys and the present, the enclosure was levelled, most likely through agricultural activity, leaving only faint traces of the original circular form. What the maps recorded, the landscape has since quietly absorbed.
