It measures roughly five metres by fifteen, and to most eyes it would read as nothing more than a slight rise in the earth. But the material beneath the surface tells a different story: black, scorched soil mixed with heat-shattered stones, the characteristic signature of a fulacht fia.

A fulacht fia is a Bronze Age cooking site, typically consisting of a trough dug into the ground, a nearby water source, and a mound of fire-cracked stone that accumulated as heated rocks were used to bring the water to boiling point. The stones fracture with repeated heating and cooling and become useless for further use, so they were simply discarded into a growing pile beside the trough. Over time, that pile darkens with charcoal and organic material, producing exactly the kind of mound visible here at Carrigacunna. What makes this particular site quietly remarkable is that it does not stand alone. Around 130 metres to the south-east, in the same field, lies a second fulacht fia. Two such sites sharing a single field suggests this stretch of the northern Nagle Mountains saw repeated or sustained activity during the Bronze Age, though whether the two sites were used simultaneously or in sequence is something the ground has not yet given up.
