It is an unassuming thing, barely half a metre high and less than a metre thick, yet it has survived long enough in this wet ground to remain a legible shape in the landscape, oriented to catch whatever sun the valley allows.

The enclosure measures roughly six metres north to south, with the flat side of the D running along the northern edge for about ten and a half metres. That straight northern boundary is not entirely the work of human hands; it follows the natural linear face of an outcropping of bedrock, with large slabs and stones set alongside it to consolidate the line. From there, the curving stone wall takes over, sweeping round to complete the enclosure. The interior, such as it is, is partially choked with rushes. What the enclosure was originally built for is not recorded. Enclosures of this kind in Ireland could serve any number of purposes, from containing livestock to defining a small settlement or field boundary, and without excavation or additional survey work, this one keeps its function to itself. Across the valley, the landmark of Carrignaspirroge is visible, suggesting the site was placed with some awareness of its wider surroundings, whatever its builders had in mind.
