This is a fulacht fia, a type of ancient cooking or processing site found in enormous numbers across Ireland, typically identified by a horseshoe-shaped mound of burnt and shattered stone, the debris of repeated heating. The proximity to water is characteristic; the sites almost always appear near streams or boggy ground, since their presumed function involved heating stones and dropping them into a water-filled trough.

What gives this particular spot a little extra interest is that it does not stand alone. A second fulacht fia lies roughly eighty metres to the north-west, and both were recorded in 1934 by a researcher named Bowman, who noted them on land belonging to a W. McAuliffe. The pairing is not unusual in itself, as fulachta fiadh, to use the plural, frequently cluster together, perhaps reflecting repeated use of a favourable location over long periods. The site also appears as a mound on the Ordnance Survey six-inch map produced in 1936, which suggests it was still a visible feature of the landscape at that time, even if its nature was not formally documented until Bowman's fieldwork.
