The mound is so low it might easily be dismissed as a natural undulation in the landscape, yet beneath or beside it lies evidence of something altogether more deliberate: a souterrain, the kind of stone-lined underground passage or chamber built during the early medieval period, most likely for storage or as a place of refuge in times of danger.

The site came to formal attention through the Corca Dhuibhne archaeological survey of the Dingle Peninsula, published by J. Cuppage in 1986, though local knowledge of its character as a fort predates that, with records of community awareness going back to at least the early 1950s. The enclosure it once formed part of has not survived in any visible way above ground; what remains is the mound and the souterrain recorded within it. On the Dingle Peninsula, such sites are not unusual, the peninsula being particularly dense with early medieval and prehistoric remains, but the combination here of a vanished enclosure, persistent local memory of a fort, and a surviving underground feature gives this particular spot a quietly layered quality.
