Measuring around five metres in diameter, it was recorded on the Ordnance Survey six-inch map produced in 1894 to 1895, captured in that great late-Victorian effort to document the Irish landscape in systematic detail. Today, however, it is not visible at ground level. Whatever boundary, hollow, or raised feature once allowed surveyors to identify and plot it has since been swallowed by the terrain.

Small circular enclosures of this kind are found across Ireland and can represent a wide range of origins, from early medieval ringfort annexes to livestock enclosures of much more recent date. At five metres across, this one sits at the modest end of the scale, too small to have functioned as a domestic settlement in the conventional sense, though its original purpose remains unknown. What makes it quietly interesting is precisely its ambiguity: it was real enough to be mapped by nineteenth-century surveyors working the Kerry hills, yet it left no trace that modern eyes can follow.
