These are hut sites, the remains of simple dwellings cut back into sloping terrain, with a low earthen bank built up on the exposed side to compensate. They are not dramatic ruins. There are no walls reaching for the sky, no inscribed stones. What survives is essentially the negative space of habitation: depressions in the earth where people once arranged their lives close to the Atlantic.

Four of the possible hut sites sit closely grouped near the cliff edge to the south-west of the promontory boundary, with a fifth appearing near the southern side of Coosgorm. In form, each follows the same logic: one side dug into the natural slope for shelter and stability, the other side built up with a bank to create an enclosed, roughly circular space. They range in diameter from around three to five and a half metres, modest dimensions that suggest individual shelters rather than communal structures. The sites were recorded and described by J. Cuppage in the 1986 Dingle Peninsula archaeological survey, published as part of the Corca Dhuibhne series, though no precise date of construction or period of use is established in that account. Dún Sheáin itself, whose Irish name suggests an older fortified presence, sits on a landscape long shaped by people making careful use of coastal terrain.
