That gap between cartographic record and physical examination is surprisingly common in the Irish landscape, but it gives this particular site an odd quality: it exists, in the documentary sense, as little more than a circle on a map.

A rath is an earthen ringfort, typically a raised circular enclosure defined by one or more banks and ditches, built during the early medieval period, roughly between the fifth and twelfth centuries. They served as farmsteads and status markers for the farming families who constructed them, and Ireland still contains tens of thousands of examples in varying states of preservation. The Moybella enclosure appears on both the 1841 to 1842 Ordnance Survey mapping and again on the revised sheets from 1939, which at least confirms it was a visible feature in the landscape across a century of cartographic attention. Beyond that, the record is silent; no permission to access the land was obtained, so no ground survey, no measured drawing, and no assessment of condition was ever carried out.
