There is no mound, no wall, no obvious structure, just a stain in the soil where something was repeatedly heated and discarded over what may have been centuries of use.

A fulacht fia is the term used for a class of prehistoric cooking place found in enormous numbers across Ireland, particularly in low-lying or marshy ground. The typical setup involved heating stones in a fire and dropping them into a water-filled trough to bring it to a boil, a method that leaves behind a characteristic crescent-shaped mound of shattered, heat-crazed stone. The example at Knockanemore conforms to the pattern in at least one respect: burnt material spread across a considerable area, suggesting sustained and repeated activity. Most fulachtaí fia date to the Bronze Age, broadly the second millennium BC, though some were used into the Iron Age. They are among the most common archaeological monuments in Ireland, yet individually they tend to attract little attention, partly because they rarely preserve dramatic visible remains and partly because their exact social function, communal cooking, meat processing, textile working, bathing, brewing, have been debated without firm resolution.
