These three modest cairns, arranged along an east-west terrace, are likely clearance cairns; piles of stones gathered and stacked by early farmers as they prepared the rocky ground for cultivation. The largest of the group, measuring five metres across and standing a metre high beneath its covering of heather, represents countless hours of backbreaking labour by people who worked this landscape centuries ago.

The cairns don't stand alone in their tale of early settlement. Just 80 metres to the southwest lies a hut site, possibly home to the very people who cleared these fields. Another potential dwelling sits 28 metres to the west, suggesting this terrace was once a small but active community. The relationship between these structures becomes clearer when you notice the remnants of an ancient field system, its stone walls now barely visible beneath the heather that stretches north and south of the cairns.

This collection of archaeological features at Foffanagh paints a picture of subsistence farming on what must have been marginal land even in its heyday. The careful arrangement of the cairns, their proximity to the hut sites, and their integration with the field walls all point to a organised agricultural system. While these humble stone piles might not look like much today, they represent the determination of early Irish farmers who transformed this hillside into productive land, one stone at a time.
