It is recorded, mapped, catalogued, and gone. What survives is essentially an administrative ghost: a circle on a nineteenth-century map, a measurement of roughly thirty metres in diameter, and the designation "rath", the Irish term for a ringfort, a type of enclosed farmstead typically dating to the early medieval period, built from earthen banks and ditches rather than stone, and used by a single farming family for settlement and livestock.

The earliest firm evidence for this particular site comes from the Ordnance Survey six-inch map of 1842, where it appears as a circular enclosure on that sloped ground south-west of Holeopen Bay. By the time any modern survey came to examine it, the rath had been levelled entirely, absorbed into the surrounding tillage with no visible surface trace remaining. This is not an unusual fate. Thousands of Irish ringforts, once numbering perhaps forty or fifty thousand across the island, have been ploughed flat over the centuries, their banks spread and their ditches filled in by generations of agricultural improvement. What makes this one worth noting is precisely the completeness of its disappearance against the persistence of the record, the way a thirty-metre circle on an old map is now the only thing holding the site in existence at all.
