A cropmark forms when buried ditches or walls affect the moisture and nutrients available to plants growing above them; from the air or from satellite imagery, the variation in crop colour and height draws out shapes that would otherwise remain entirely invisible.

The enclosure here was identified from Google Earth Pro imagery captured on 14 July 2018 by researchers Jean-Charles Caillère, Simon Dowling, and Edward O'Riordan. What they found was a semi-circular cropmark representing the south-eastern arc of what was probably a roughly circular enclosure, measuring approximately 32 metres on its north-east to south-west axis and around 16 metres on the north-west to south-east axis. The north-western portion has likely been obscured or destroyed by a field boundary that cuts across the site in the same north-east to south-west direction. Circular enclosures of this kind are a common feature of the Irish landscape, often interpreted as the remains of ringforts, the farmstead enclosures used widely from the early medieval period onwards, though without excavation it is impossible to say with certainty what purpose this particular site served or when it was built. Roughly 95 metres to the south-east lies a second cropmark enclosure, suggesting that whatever activity once defined this corner of Kilkenny, it was not isolated to a single site.
