It is small enough to walk past without a second glance, yet it almost certainly marks a prehistoric burial. The mound is subcircular in shape, roughly eight metres across east to west and seven metres north to south, and rises to less than a metre at its highest point. Its top is notably flat, a quality that sometimes indicates deliberate construction rather than natural accumulation. Where grass has not crept over it, the exposed material consists mostly of flat slabs, the kind of limestone flags that are characteristic of the Burren landscape.

The site sits within what surveyors describe as a relict field system, the ghostly outlines of ancient agricultural boundaries that have survived in the terrain long after the people who made them are gone. A cairn of this kind, a mound of stones heaped over a burial or a cist (a stone-lined grave cut into the ground), would not be unusual in a prehistoric landscape that also organised itself into fields and enclosures. The connection between the two features at Fahee is suggestive, though not proven. The site was formally listed as a burial mound in the Record of Monuments and Places in 1996, drawing on an earlier map annotation noting a mound and cist by Tom Coffey, and a separate reference to a cairn by Paul Walsh. On the northern upper slope, a large upright slab leans heavily to one side, standing about 0.6 metres high, with smaller slabs around it. A further cluster of flat slabs appears on the upper slope to the east-southeast. A slight hummock extends outward from the eastern edge of the cairn itself, the ground rising just enough to suggest something more lies beneath.

The terrace faces south, which means wide views open out across the landscape in most directions, with only the ridge rising to block the north. The mound would have been conspicuous when first raised, a deliberate marker in an organised landscape. It is less conspicuous now, half-buried in turf and unremarked on most maps, which is perhaps part of what makes finding it worthwhile.
