Low earthen banks, filled-in ditches, the ghost of a drystone wall, a faint fosse, which is a defensive ditch typically dug to protect a fortified enclosure: the traces are slight enough that no firm conclusion has ever been drawn about them. That ambiguity is itself part of what makes this stretch of coast quietly compelling.

A survey note recorded in 2002 by Casey describes the six headlands carefully and without false confidence. The two northernmost show low earthen banks and the remains of a levelled drystone wall crossing the neck of land that connects each headland to the shore. The adjacent broad rectangular headland retains what appears to be a wide, levelled bank and a faint fosse across its neck. The southernmost of the six is defended, if that is the right word, by a slightly curving fosse that has since been filled in. The middle two are cut off by earthen banks that appear to be recent, though vaguer traces beneath them hint at something older. Promontory forts were a common form of coastal enclosure in prehistoric and early medieval Ireland, using the natural defensibility of a headland and adding an earthwork or wall only where the land connected; the difficulty here is that so little survives that the category itself remains uncertain. Casey concluded that all six headlands deserve further investigation, a phrase that in archaeological terms carries real weight.

The site sits in Ard Na Caithne, a coastal area on the Dingle Peninsula. Visitors walking this stretch of coastline would be looking for subtleties rather than monuments: a slight rise in the ground at a headland neck, a linear depression that does not quite match the surrounding terrain, a scatter of stones arranged a little too regularly to be coincidental. Whether these are the weathered remains of an organised defensive system or the cumulative result of farming and field clearance over centuries is a question that remains, for now, genuinely open.
