That consistency of recording, across generations of cartographers, suggests something quietly deliberate about this modest mound, even if its origins and purpose have never been fully explained.

The cairn, a term for a mound of stones typically raised in prehistoric or early historic times, sometimes as a burial marker and sometimes as a territorial or commemorative landmark, is subcircular in plan and tapers to a point at its summit. Its dimensions are modest: roughly 3.3 metres along its northeast to southwest axis, 2.7 metres across from northwest to southeast, and just 0.8 metres high. It is, in short, a small thing, the kind of feature that would be easy to walk past without registering its age or intention. The stones themselves are small and loose, with no obvious structural courses or kerbing visible in the recorded description.

What makes it worth noting is less what it is than where it is and how persistently it has been acknowledged. Lough Naweelion sits in genuinely wild ground, and the cairn occupies the lakeside edge of that landscape. The fact that it appears on all Ordnance Survey editions points to a long-held local awareness that this was not simply a field clearance or a natural scatter of stone, but something placed, and worth preserving on the map.
