Spread across roughly sixteen hectares of farmland, a series of rectilinear cropmarks, some running perpendicular to one another, trace out what was once an organised field system. Cropmarks form when buried features such as ditches, walls, or paths affect the moisture and nutrient content of the soil above them, causing the crops or grass growing at the surface to flourish or wither in patterns that mirror what lies underneath. The result, seen from altitude, is a kind of ghost map of an earlier agricultural world.

The pattern was captured in aerial photographs taken in July 1989 as part of a systematic survey of the Cork region. Within the broader arrangement of field boundaries, some groupings of closely spaced parallel lines have been interpreted as possible routeways, suggesting this was not simply a patchwork of enclosures but something more like an integrated working landscape, with movement built into its design. To the north of the field system lies a separate circular enclosure, a form commonly associated with settlement or ritual use across prehistoric and early medieval Ireland, hinting that the fields may have been connected to a nearby habitation site rather than existing in isolation.
