A fulacht fia, the term for a type of ancient outdoor cooking or heating place typically identified by a horseshoe-shaped mound of fire-cracked stone beside a trough or pit, is believed to lie somewhere within a small unplanted buffer zone at Caher. The catch is that no visible surface trace of it can currently be confirmed, and the area has become so overgrown that pinpointing the monument precisely is, by any reasonable measure, very difficult.

The site came to attention in 2000, when Michael Connolly, County Archaeologist with Kerry County Council, carried out an assessment across a 40-square-mile area north of Killarney as part of a road route selection process. During that survey, he identified this location as one of seven fulachta fia still considered to be extant in the area. The monument is thought to lie within a forestry buffer zone, a strip of unplanted land left between commercial forestry planting and other ground. That zone is now hemmed in by post-and-wire fencing to the west and north, commercial forestry beyond that, and field boundaries to the east and south. Because the ground is ungrazed, vegetation has been allowed to accumulate unchecked, and what might once have been a low, readable mound is now thoroughly obscured.

There is something quietly interesting about a site that exists, officially, as a possibility rather than a confirmed presence. It was recorded, assessed, and noted as likely real, but the ordinary processes of land management and plant growth have, for now, placed it beyond easy reach or verification. The fencing is not archaeological in purpose; it simply marks the edge of a commercial forestry operation. The archaeology, if it is there at all, sits behind it in the undergrowth, unexcavated and unmeasured.
