Running in a gentle curve from north-northeast to south, a farm fence at Meens may be quietly preserving the last visible remnant of a circular enclosure that is otherwise invisible to anyone standing on the ground. Only from the air does the fuller picture emerge.

In May 1977, an aerial photograph captured a cropmark tracing an arc of what appears to be a fosse, the outer ditch of a roughly circular enclosure approximately forty metres in diameter. Cropmarks appear when buried features such as ditches or banks affect how vegetation grows above them, producing patterns of differential colouring that can only be read from altitude. The arc runs from south around to north-northeast, and the curving field fence picking up from there may follow the line of an original earthen bank, absorbed into the agricultural landscape over centuries. Enclosures of this type and scale are commonly associated with early medieval settlement in Ireland, though without excavation it is impossible to say more about the date or purpose of this particular site.
