What people call a fort is, in fact, a clochan, a small drystone corbelled hut of a kind built without mortar, where each course of stones is laid slightly inward until the courses meet at the top. This one sits on a fairly steep and uneven slope above Dunquin, with the Blasket islands visible across the water to the west. It is roughly oval, measuring 3.5 metres by 2.7 metres internally and standing to about 1.5 metres in height, which means it is more of a crouch than a stand inside.

What makes the structure particularly interesting is the recess that opens off its western wall. Also corbelled and still retaining its roof, this chamber is U-shaped in plan, with an entrance just over a metre wide and a metre high, opening into a space that rises to 1.5 metres inside and extends 1.7 metres back into the thickness of the structure. Two low upright slabs act as a sill across the entrance. The combination of the main hut and this internal recess gives the whole thing an unexpected complexity for something so small. The site was documented in J. Cuppage's 1986 archaeological survey of the Dingle Peninsula, Corca Dhuibhne, which remains a foundational reference for early structures in this part of Kerry. Clochans of this type are closely associated with early medieval monastic and hermit traditions on the western seaboard, and several survive on the Dingle Peninsula and the Skellig islands further south, though the exact dating of any individual example is rarely straightforward.
