A cropmark, the faint differential in how crops grow over buried ditches and disturbed soil, betrays the outline of a roughly circular feature roughly 45 metres across, its presence recorded in an aerial photograph taken in 1989. What makes it quietly odd is the southern side: where the rest of the boundary curves, that stretch runs straight for approximately 30 metres, an anomaly that sets it apart from the standard ringfort or enclosure form.

The enclosure is defined by a fosse, a term for a rock-cut or earthen ditch that would originally have marked a boundary, whether for a settlement, a farmstead, or something with a more ceremonial purpose. The site does not sit in isolation. Around 160 metres to the north-north-west lies a ring-ditch, a circular trench that in Irish archaeology is frequently associated with prehistoric burial, often the surviving remnant of a levelled burial mound. A further 200 metres to the south-west, another ring-ditch sits within a large enclosure, suggesting this corner of Kilkenny was once a landscape with layered and overlapping uses across different periods. Whether these features are contemporary with one another or separated by centuries is not something the aerial evidence alone can settle.
