It is, in fact, the surviving wall of an ancient hut site, its three courses of unhewn stone still holding their rough shape after what may be centuries of exposure to Atlantic weather.

The structure is modest in scale, measuring 4.6 metres north to south and 3.6 metres east to west, with the wall reaching a maximum height of 0.6 metres. The individual boulders are unworked, the largest measuring around 0.45 metres across, placed rather than dressed. A separate arc of low walling curves away to the north-east and butts up against the outer face of the hut wall along its north-eastern arc, suggesting either a secondary enclosure, a windbreak, or perhaps an addition built at a different time. Hut sites of this kind are generally understood as the remains of simple shelters associated with seasonal farming activity, such as the summer grazing practice known as booleying, though without excavation it is impossible to date this example precisely or assign it a definitive function. What can be said is that whoever built it chose the spot carefully: the grassy platform offers a natural break in the slope, and the southward orientation would have made it as sheltered and warm as the hillside allowed.
