Somewhere beneath reclaimed pasture in mid-Cork lies what was once a fulacht fia, a type of prehistoric cooking site found in enormous numbers across Ireland, typically identified by a horseshoe-shaped mound of heat-shattered stone and charcoal built up over centuries of use. The mound here stood roughly a metre high before it was levelled around 1982, leaving no visible surface trace. The archaeology is gone, or at least buried and disturbed, and the field has moved on.

Fulachtaí fia, the plural form, are among the most common ancient monuments in Ireland, dated mostly to the Bronze Age. They generally cluster near water sources and are thought to represent outdoor cooking places, where stones were heated in fire and then dropped into water-filled troughs to bring the water to a boil. The Killaclug example followed the familiar pattern: a mound of burnt and cracked stone, the discarded residue of repeated heating. What made such sites visible in the landscape for so long, sometimes for three or four thousand years, was simply the durability of that scorched material, which no one had much reason to move until modern land improvement gave them reason enough. In this case, local information recorded that the levelling happened in 1982, which at least fixes the moment of loss with some precision.
