The remains are modest, easy to miss, and slowly losing ground to the sea, which has already claimed part of one structure. That quiet erosion is, in its own way, part of the story.

The complex consists of a rectangular hut-site measuring roughly 3 by 4.5 metres, tucked against a bank at the promontory's south-eastern end. A later wall, accompanied by a slight internal fosse (a shallow defensive ditch), runs along the cliff edge, cutting off two smaller promontories to the south and south-west. On the western edge of one of these sits a D-shaped enclosure, just 2.2 by 2 metres, with low banks less than 0.3 metres high; its western side has already fallen into the sea. Nearby, a larger hollow in the ground appears to be the result of quarrying, possibly dug to provide stone for the later defensive walls. A promontory fort is a specific type of early Irish enclosure in which natural cliff edges do much of the defensive work, with walls or banks constructed only where the terrain offers no protection. The defences here are slight, but the arrangement of structures and, most tellingly, the local Irish name for the site, An Dúinín, meaning something like "the little fort", point firmly in that direction. The name was recorded by the scholar and writer An Seabhac in 1939, and it suggests a living memory of the site's function long after the stones had settled into the grass. The site was surveyed and described by J. Cuppage as part of the Dingle Peninsula archaeological survey published in 1986.
