The Ordnance Survey's first edition of 1836 recorded it as a large ring, and then, on every survey that followed, it simply vanished from the record. No later cartographer marked it. Whether it was demolished, absorbed into farmland, or dismissed as unreliable by subsequent surveyors, no one now says.

Circular enclosures of this kind are a familiar feature of the Irish landscape, though their purposes vary considerably. Some are the earthen remnants of early medieval farmsteads, the banks and ditches that once defined a family's living space. Others are burial monuments of far greater age. Without further investigation at Kiffagh, the function of this particular enclosure remains an open question. What can be said is that the 1836 Ordnance Survey, the first systematic large-scale mapping of Ireland, was meticulous enough to record something here that later editions ignored entirely, which suggests either that the feature was already degrading by the mid-nineteenth century or that it was simply not considered significant enough to carry forward.
