Four mounds once stood here in a marshy field at Carhoobeg, composed of stone, until the 1950s when land reclamation work levelled them entirely. What remains are scatters of burnt stone across the field, the kind of material debris that archaeologists associate with fulachta fiadh, a term referring to prehistoric cooking sites, typically Bronze Age, where stones were heated in fire and dropped into water-filled troughs to bring them to the boil. The method was efficient, the evidence lasting: discarded cracked and fire-reddened stone tends to accumulate into the low, rounded mounds that are among the most common prehistoric monuments found across Ireland.

The landowner at the time of the clearances recalled the mounds being made of stone, which aligns with the usual composition of a fulacht fia site. Whether the four mounds at Carhoobeg were used together, at different periods, or represented accumulated activity over generations is now impossible to say with certainty. The river proximity matters: water access was essential to the cooking process, and marshy, low-lying ground beside a river is exactly where these sites tend to cluster. The River Laune, flowing westward out of Lough Leane near Killarney, would have provided a reliable water source. The reclamation work of the 1950s, driven by post-war efforts to bring marginal land into agricultural use, erased the physical structures before any formal investigation could take place, leaving only the scorched residue in the soil as evidence of what had been there.
