The mound is gone, levelled away, but a spread of burnt material remains in the earth, the quiet residue of a practice that was once widespread across the Irish landscape.

A fulacht fia is a type of ancient cooking site found in enormous numbers throughout Ireland, typically dating from the Bronze Age, roughly 1500 to 500 BC, though some examples are earlier or later. The standard form consists of a horseshoe-shaped mound of fire-cracked stones and charcoal built up beside a water source, with a nearby trough, usually timber-lined or cut into clay, in which water was heated by dropping in stones from a fire. The heat transferred efficiently enough to boil meat and, experiments have shown, to cook it quite thoroughly. The proximity to running water was essential, both for filling the trough and for keeping the area workable. At Garraun, the stream to the west of the site would have served exactly this function, and the scorched, fragmented stone that remains in the soil is the accumulated waste of that repeated heating and quenching process, stone that cracks and becomes useless after a few cycles and is simply discarded to one side. Thousands of such sites survive across Munster in particular, making the fulacht fia one of the most common monument types in Irish archaeology, yet each individual example tends to attract little attention precisely because it is so ordinary within the broader record.
