The enclosure here exists primarily as a cropmark, a phenomenon where buried ditches and banks influence the growth of crops or grass above them, producing ghostly outlines that only become legible from the air. In a July 1989 aerial photograph, the fosse, meaning the ditch that once defined the boundary of a settlement or enclosure, traces out a subrectangular shape roughly 20 metres across on its east-west axis. Adjoining its south-east corner is a smaller, roughly circular annexe, its own fosse visible as a separate cropmark. Two shapes pressed faintly into the landscape, readable only by someone looking down from above.

What makes the site more than a solitary curiosity is its context. The Moyge enclosure is one of five such enclosures clustered together, all of them sitting within the boundaries of a broader field system. That combination, multiple enclosures associated with an organised agricultural landscape, points toward a settlement pattern typical of early medieval Ireland, where ringforts and their associated enclosures were often grouped rather than isolated. The subrectangular form here is somewhat less common than the purely circular ringfort, and the presence of a distinct annexe off the main enclosure suggests a secondary function, perhaps for livestock, storage, or a related domestic space. Without excavation it is impossible to say more with certainty, but the aerial evidence alone places this firmly within a recognisable tradition of enclosed rural settlement.
