What makes this arrangement quietly unusual is the contrast between the two: the north-western arm survives mainly as a linear depression, its original bank levelled flat on either side, while the south-eastern arm is still physically present as a raised bank some ten metres wide, standing around a metre tall on its interior face and rising to about one and a half metres on its exterior edge. Together they measure less than eighty metres in total length, yet their geometry and their relationship to the enclosure suggest something deliberately planned rather than incidental.

The site was formally identified during a field inspection in December 2006, and it appears to be associated with a nearby sub-circular or wedge-shaped enclosure. Linear earthworks of this kind, sometimes called linear banks or field boundaries, are found at various periods in Irish archaeology, and their precise function is often difficult to establish without excavation. They may have defined land divisions, guided movement of livestock, or marked boundaries of significance in the local landscape. The south-eastern bank seems to have been cut short by a later field boundary to the south, which is a common fate for earthworks that survived long enough to be absorbed into the working agricultural landscape of post-medieval and modern farming. The levelling of the north-western arm tells a similar story of slow erasure, its banks gradually reduced until only the central depression remained to trace the original line.
