A circular enclosure, roughly thirty metres across, shows up not as a visible earthwork but as a cropmark, the kind of ghostly outline that only becomes legible when viewed from altitude and under the right conditions. Cropmarks form when buried features such as ditches or walls affect how plants grow above them, producing subtle differences in colour and height that are invisible at ground level but readable in aerial photography. This one is defined by a fosse, an enclosing ditch, and would almost certainly have gone unnoticed by anyone simply walking the land.

The site came to light through an aerial photograph, reference GB89.AC.03, which captured the circular outline along with a second, curvilinear enclosure immediately to the south. The two together suggest this corner of County Tipperary was once a structured, organised place, though what exactly it was used for is not recorded. Circular enclosures of this kind are commonly associated with early medieval settlement in Ireland, ringforts being the most familiar example, though enclosures could also serve agricultural, ritual, or funerary purposes. Without excavation, the specific function here remains open. What is clear is that the fosse-defined outline and its neighbour to the south represent some deliberate shaping of this landscape, now buried beneath ordinary farmland on the edge of a town better known for its medieval walls and friary.
