This is Cathair Deargáin, a cashel, meaning a stone-walled ringfort of early medieval date, and its beehive-shaped inhabitants, known as clochans, are among the better-preserved examples of their kind in Kerry. The whole settlement sits on a west-north-westerly facing hillside with a wide view across the northern side of the peninsula, a position that would have made practical sense both for shelter from the prevailing wind and for keeping watch over the landscape below.

All five huts are circular or sub-circular in plan and built using the corbelling technique, in which each course of unmortared stone projects slightly inward over the one below until the gap at the top is narrow enough to be sealed. No mortar, no timber, no fired brick; just careful geometry in local stone. The largest of the five, measured internally at roughly six metres by five and a half metres, stands out from the others in more than size. Its outline is less regular, its walls rise to about one and a half metres, and two of the other huts open directly off its sides. The entrance, less than half a metre wide, faces north-north-east. Researchers have noted that this larger structure may not have functioned as a roofed hut at all; the slightly corbelled walls could indicate a roofed space, but the irregular plan and the way the other huts attach to it raise the possibility that it served as an open courtyard instead. The enclosure also contains one or possibly two souterrains, underground stone-lined passages that were typically used in early medieval Ireland for storage or as places of refuge. J. Cuppage documented the site as part of the Dingle Peninsula archaeological survey published in 1986.
