It is, in fact, a fulacht fia, a type of prehistoric cooking site found in great numbers across Ireland, typically dating from the Bronze Age. The usual interpretation is that such sites were used to boil water by heating stones in a fire and dropping them into a water-filled trough; the shattered, fire-cracked stones that accumulate from repeated use are what form the characteristic horseshoe-shaped mound. This particular example is modest, measuring roughly six metres long, one and a half metres wide, and half a metre high, its irregular shape suggesting it has been disturbed over time, at least in part by the unsurfaced track that now cuts through it.

What makes this spot quietly interesting beyond its own modest dimensions is its proximity to a second fulacht fiadh, which lies just ten metres to the north-east. The clustering of these sites is not unusual; fulachtaí fia are often found in pairs or loose groupings, likely because the boggy, water-retentive ground that made one location practical for their use made a neighbouring spot equally suitable. Together, the two sites hint at repeated, perhaps seasonal, activity in this corner of Cork over a long stretch of prehistoric time, even if the precise nature of that activity, cooking, bathing, textile processing, or something else entirely, continues to be debated by archaeologists.
