The ringfort at Gortaneare, recorded under the townland name Lisanrahan, is one such place. A univallate rath, meaning a ringfort enclosed by a single earthen bank and ditch, it would once have formed the defended farmstead of an early medieval family, a form of settlement that was once so common across Ireland that thousands survive in some condition today. This one does not.

The rath appears on the Ordnance Survey maps of 1841 to 1842 and again on the 1916 edition, which tells us that it was still sufficiently visible in the nineteenth and early twentieth centuries to be recorded by surveyors working across the landscape. At some point between 1916 and the present, it was levelled entirely, most likely through agricultural clearance. C. Toal's North Kerry Archaeological Survey, published in 1995, notes that no visible trace remains. The site exists now only as a named point on older maps and as an entry in the archaeological record, a placeholder for something that was once a functioning settlement and is now indistinguishable from the surrounding land.
