The feature is easy to overlook, a modest oval pit in ground that was never meant to stay dry, but the charcoal-rich deposits and heat-shattered stone filling it point toward something much older than the surrounding agricultural landscape.

A fulacht fia, for those unfamiliar with the term, is a type of ancient outdoor cooking site found widely across Ireland, typically consisting of a water-filled trough into which heated stones were dropped to boil the contents. They are generally associated with the Bronze Age, though their precise function has been debated. Pre-development testing at this site in 2009, carried out by Colm Moriarty under licence number 09E0420, identified the feature, catalogued as F 12, in what the report designates as Field 2. The pit measured 1.4 metres in length and 0.5 metres in depth, and its fill of burnt stone and charcoal-rich soil closely resembles the spreads of debris, known as burnt mound material, that accumulate around fulacht fia sites over repeated use. Moriarty and Gowen's 2009 report stops short of certainty, describing it as a possible cooking trough, a cautious reading appropriate given the limited extent of the testing.

The site lies in ground prone to flooding near the Camac, which runs through parts of west County Dublin before joining the Liffey. Access to the immediate location is not straightforward, as it sits within a field examined ahead of development rather than at a publicly maintained heritage site. The find is perhaps most useful as a reminder of how frequently such features turn up just below the surface of ordinary agricultural land, revealed only when ground is disturbed for construction, and then documented carefully before being lost again.
