The Ordnance Survey mapped it in 1842 simply as a "Sheep Fold", a label that feels practical enough until you start measuring. The enclosure is rectangular, with a north-south bank running eighteen metres and an east-west bank of eight and a half metres, the latter surviving to a height of sixty centimetres. Those are substantial earthworks for a fold, and the site's classification as an archaeological enclosure rather than a routine agricultural feature reflects a degree of uncertainty about what, exactly, was being enclosed here and when.

An earthen enclosure of this kind, formed by raised banks rather than stone walls, is a construction type found across Ireland from prehistory well into the early medieval period, used variously for settlement, ritual, or livestock management. The honest answer at Cousane is that the notes do not resolve the question. What survives is partial: the eastern side of the north-south bank continues southward for about six metres, and the whole structure is interrupted by numerous gaps, each around two metres wide, which may represent original entrances, later breaches, or simple collapse over time. The 1842 survey name suggests that by the nineteenth century local memory had settled on a functional, agricultural explanation, though such names often reflect reuse rather than original purpose.
