That bank, roughly three metres wide and curving to follow the line of the promontory, is the primary reason this place is considered a fort at all. Promontory forts are among the more elemental structures in the Irish archaeological record, using the natural defensibility of a headland and adding only what was strictly necessary, typically a bank, a ditch, and a way in. Here, the outer fosse, the ditch that would once have sat in front of the bank, is only intermittently visible now, and a gap near the eastern cliff edge hints at where an original entrance once stood.

The site was recorded in 2002 by Casey, who described a subrectangular headland measuring 70 metres long by 37 metres wide, northeast-facing and ridge-backed, sloping steeply down to a point. The bank sits 18 metres from the neck of the headland, the narrowest point where the land pinches before opening out again. The interior undulates but offers no obvious features to read; whatever activity once took place within the defended area has left no clear trace at the surface. The surrounding land is fertile pasture, the site is overlooked by higher ground inland, and a neighbouring headland to the west sits close enough to make the position feel both exposed and watched.

The earthen bank and the faint fosse are most legible in low, raking light, when shadows pick out the slight variations in the ground that are otherwise easy to walk across without noticing. The gap near the cliff edge rewards attention too, though the cliff itself demands care.
