It may, or may not, be the entrance to a souterrain, an underground passage or chamber of the kind commonly associated with early medieval settlements in Ireland, used for storage or as a place of refuge. That single unresolved detail says a good deal about the site as a whole: much of what lies within remains uncertain, not because the archaeology is absent, but because the vegetation is simply too thick to allow a proper look.

The fort is known as Lisgortcam, or Lios Gort Cam in Irish, a univallate rath, meaning a ringfort enclosed by a single bank and ditch rather than multiple concentric rings. Its internal diameter runs to roughly 26 metres north to south and 29 metres east to west, placing it within the typical size range for a farmstead enclosure of the early medieval period. The enclosing bank, built from earth and small stones, survives to a maximum external height of about 1.5 metres, though it is badly eroded and disturbed throughout. The northern section retains traces of drystone walling on its inner face, while the southern section has had later stonework, up to 1.7 metres high, built against its outer face, repurposing part of the ancient boundary as an ordinary field wall. Near the centre of the interior, what appears to be the remains of an animal pen can be made out, and the western sector holds an irregularly shaped stony ridge of unknown origin. J. Cuppage documented the site in the 1986 Dingle Peninsula archaeological survey, and the difficulties he encountered in examining it have not obviously improved since.
