This one is remarkable for what does not. On the north bank of a small stream in Dromaloughane, on the Iveragh Peninsula in County Kerry, an enclosure once appeared on the first edition of the Ordnance Survey map, that great nineteenth-century effort to document the Irish landscape in meticulous detail. The site was subcircular in shape, the kind of roughly rounded boundary, typically formed from an earthen bank or stone wall, that recurs across Ireland in various forms and periods. It sat in ground prone to flooding, which may say something about how the land was used, or simply about the limits of where boundaries got drawn.

The enclosure is gone now. Land reclamation work carried out in the 1970s erased whatever physical trace remained, leaving only the cartographic record as evidence that something was ever there. Whether it was a ringfort, a field enclosure, a settlement boundary, or something else entirely is not known. Its antiquity remains uncertain, and without the earthworks to examine or excavate, that question is unlikely to be resolved. It exists now as a kind of ghost on the map, a feature that was recorded before it was lost, which is more than can be said for many sites that disappeared without anyone noting them at all.
