The cartographers who produced the Ordnance Survey six-inch map in 1838 marked it clearly enough, a roughly circular form sitting in level pasture. By the time later map editions were produced, it had disappeared from the record entirely, and today there is no visible trace of it at ground level.

Circular enclosures of this kind are a common enough feature of the Irish landscape, ranging from prehistoric ring forts to early medieval farmstead enclosures, and their absence from the surface tells you relatively little. Some were levelled by generations of agriculture, others were never more than earthen banks that the plough gradually erased. What is unusual here is the gap in the cartographic record itself. The 1838 OS six-inch mapping was a remarkably thorough enterprise, conducted with considerable care for earthworks and field boundaries, so the presence of this feature on that survey and its subsequent disappearance from later editions raises a quiet question: was it already degrading when the first surveyors passed through, noted, and moved on, or did something more deliberate account for its removal from the landscape in the decades that followed?
