The land here slopes gently down towards the River Suir, and has long since been reclaimed and put to agricultural use. Nothing breaks the surface to suggest that anything lies beneath. The only reason anyone knows something is there at all is a single aerial photograph.

Taken on 16 July 1989, that photograph revealed a cropmark, the kind of faint differential growth in vegetation that can betray buried features to a camera looking straight down. Cropmarks form when buried ditches or walls affect how soil retains moisture, causing the grass or crops above them to grow differently from their surroundings, usually only visible under the right atmospheric conditions and from altitude. What the photograph showed was part of a possible curvilinear enclosure, its outline defined by a fosse, an earthwork ditch, curving across the ground below. A curvilinear enclosure of this kind is a broad category in the Irish archaeological record, potentially associated with early settlement, ringfort activity, or ceremonial use, though without excavation it is impossible to say more. The River Suir runs roughly 270 metres to the northwest, a detail that would have mattered to whoever chose this spot, whenever that was.
