Enclosures of this kind, low-walled roughly circular or oval structures, are common enough across the Irish countryside, often interpreted as animal pens, shelters, or the foundations of simple domestic buildings. Finding four of them together in one place, each only a few metres across, is less common, and the grouping raises questions that the landscape alone cannot answer.

The structures were recorded as part of the archaeological survey of the Iveragh Peninsula, compiled by A. O'Sullivan and J. Sheehan and published by Cork University Press in 1996. The four foundations are roughly constructed, with walls that have survived to modest heights, between roughly 30 and 50 centimetres above ground, and at their thickest not quite a metre. Their entrances are poorly defined, which makes it difficult to determine orientation or function with any confidence. One of the enclosures is particularly distinctive in that it incorporates a large natural rock outcrop into its northern wall, a practical choice that reduced the amount of stone that needed to be gathered and laid, and suggests builders who were working with the landscape rather than imposing uniformity on it. The site lies south-east of the townland feature known as Knocknabreeda, on ground that would have been marginal but not unusable, the kind of terrain that was often exploited for seasonal grazing or small-scale agricultural activity.
