What we know of it comes almost entirely from a single aerial photograph.

The enclosure was identified as a cropmark on a photograph taken on 19 July 1967 as part of the Cambridge University Collection of Aerial Photography (reference CUCAP ATS012). Cropmarks form when buried features, ditches, walls, or pits alter the moisture and nutrient content of the soil above them, causing the vegetation at the surface to grow differently, sometimes visibly so from the air even when nothing is detectable at ground level. In this case, the enclosure is defined by a fosse, a broad ditch, whose course appears clearly in the photograph. The site does not exist in isolation. A cairn, a heap of stones that may mark a burial or serve as a field clearance monument, sits within the north-west quadrant of the enclosure, though it was already obscured by scrub when the photograph was taken. A modern field boundary and farm roadway cut through the western side of both the enclosure and the cairn, suggesting the landscape has been worked and reworked without any apparent awareness of what lay beneath. More intriguing still, the photograph reveals a narrow roadway formed by two parallel ditches running roughly north-east to south-west for approximately 160 metres, meeting the enclosure at its south-west perimeter. Faint curvilinear marks to the north-west may indicate a second enclosure or the remnants of an associated field system, though their precise nature remains uncertain.

Taken together, the features suggest a complex of activity, possibly prehistoric or early medieval in origin, that once organised this stretch of Kilkenny countryside in ways now almost entirely erased. The enclosure itself remains invisible at ground level, its geometry legible only from above, and only on the right day, in the right light, when the crops choose to remember what is buried beneath them.
