This is a univallate rath, meaning an enclosure defined by a single bank and ditch, a form of defended farmstead common in early medieval Ireland. What makes this particular example quietly compelling is what lies within: the traces of three separate hut sites, and the possible remains of a souterrain, an underground stone-lined passage typically used for storage or as a refuge, that may once have run beneath the enclosure.

The site sits at An Gabhlán Beag in County Kerry, on an east-south-east facing slope with a natural outlook over the river below. J. Cuppage documented it in the 1986 Corca Dhuibhne archaeological survey of the Dingle Peninsula, a thorough catalogue of the extraordinary density of prehistoric and early historic monuments found across that landscape. Three hut sites are associated with the rath interior. The third of these, noted by a researcher named Curran, survives only as a shallow circular depression roughly five metres in diameter, situated to the east of one of the other structures. It is the kind of feature that reads as unremarkable ground-level variation to an untrained eye, but represents the faint floor plan of a dwelling that would once have been a working part of this small enclosed community. The souterrain associated with the site is mentioned only briefly, its precise relationship to the enclosure not fully resolved.
