What makes them quietly odd is not their age or drama but their informality. The walls are roughly constructed, the entrances poorly defined, and one of the structures incorporates a large natural rock outcrop directly into its northern side, as if whoever built it decided the landscape itself could do some of the work.

The enclosures lie southeast of Knocknabreeda, and their remains are modest by any measure. The best-documented of the four measures roughly 6.6 metres by 6.2 metres, with walls surviving to only 0.3 metres in height and about 0.6 metres in thickness. Enclosures of this kind, essentially defined areas bounded by low stone walls, appear across the Irish countryside in various forms and periods, sometimes associated with settlement, sometimes with the management of livestock or land. The rough construction here and the lack of clear entrances do not make identification easy, and the site sits in the kind of marginal, waterlogged ground that tends to preserve archaeology while discouraging closer investigation. A. O'Sullivan and J. Sheehan documented the site as part of their survey of the Iveragh Peninsula, published by Cork University Press in 1996, which remains one of the more thorough regional archaeological records in the country.
