A circular enclosure, roughly twenty metres across, was recorded by the Ordnance Survey's first edition six-inch map of 1839, dutifully plotted by the cartographers who passed through during that remarkable early Victorian project to map the entire island. By the time the surveyors returned for the 1900 to 1901 revision, it was gone, or at least no longer considered worth marking. Today, nothing is visible at ground level.

Circular enclosures of this kind are common features of the Irish countryside, ranging from prehistoric ring ditches to early medieval ringforts, the latter being enclosed farmsteads typically defined by an earthen bank and ditch. At twenty metres in diameter, this one would have been on the modest end of the scale. What it actually was, how old it was, and why it disappeared from the cartographic record between one survey and the next are questions the surviving evidence cannot answer. It may have been ploughed out, eroded away, or simply reassessed by later surveyors as too faint to record. The 1839 mapping was in some ways the first systematic attempt to capture such features across Ireland, and not everything noted then survived long enough to be confirmed.
