The site is a fulacht fia, a type of prehistoric outdoor cooking place found widely across Ireland, typically consisting of a water-filled trough into which stones were heated in fire and then dropped to bring the water to a boil. They are among the most common archaeological monument types on the island, yet each excavation tends to add something precise and quietly remarkable to what we know about Bronze Age life.

When archaeologists opened the south-eastern quadrant of the Ballyremon Commons site following that 1983 disturbance, they uncovered a sub-rectangular trough, clay-lined and carefully shaped, measuring just over two metres in length, narrowing slightly from top to base, and roughly forty centimetres deep. It was filled with the characteristic debris of fulacht fia use: peat and burnt stones, the latter the cracked and fire-shattered residue of repeated heating cycles. More striking were three charred wooden stakes found at the base of the pit. One of these was submitted for radiocarbon dating, returning a result of 3410 plus or minus 40 years before present, uncalibrated, placing activity at the site somewhere in the middle Bronze Age. The find was published by Buckley in 1998. The stakes themselves are unusual; their function at the base of the trough is not entirely clear, though they may have served a structural role in stabilising or lining the pit.
