Known locally as Faha Fort or Lios na Faiche, meaning the ringfort of the lawn, it occupies the corner of a field in Garrynaneaskagh, Co. Kerry, where its earthen bank still rises to a maximum of four metres above the fosse. That fosse, the external ditch that was dug to create the bank material, is steep-sided and U-shaped, particularly well preserved on the western through northern to eastern arc, where it measures between 1.4 and 2.7 metres wide and reaches a depth of nearly four metres in places.

Ringforts of this kind, circular enclosures defined by an earthen bank and ditch, were built predominantly during the early medieval period, roughly between the fifth and twelfth centuries, and functioned as enclosed farmsteads for farming families of varying social rank. This example is univallate, meaning it has a single enclosing bank rather than two or three, and spans roughly 35 by 36 metres internally. At some point in recent decades, the landowner Mr Royal reported that a souterrain was uncovered in the eastern sector of the interior. A souterrain is an underground stone-lined passage, typically associated with storage or refuge, and their presence within ringforts is relatively common across Ireland. Whatever was briefly exposed here is no longer visible, having since been covered over again, leaving the interior overgrown and its underground feature quietly sealed beneath the surface once more.
