It measures roughly five and a half metres across and barely a tenth of a metre high, its surface softened by vegetation. What lies beneath is a fulacht fia, a type of prehistoric cooking site found in enormous numbers across Ireland, typically recognised by the crescent-shaped or horseshoe mound of heat-shattered, fire-blackened stone that accumulates around a central trough over repeated use. The method, as best understood, involved heating stones in a fire and dropping them into a water-filled pit to bring it to a boil. The stones crack with repeated thermal shock and are discarded to the sides, building up the characteristic mound over time.

What makes this particular site more than just a single roadside curiosity is its immediate company. It is one of four fulachta fiadh recorded in the same field, the others clustered close enough to suggest this patch of wet ground was returned to repeatedly, perhaps across generations. Marshy locations are typical for these sites; the proximity to a reliable water source was essential to the whole process. The concentration of four in one field is a reminder that these monuments, though individually modest, were not isolated events. They represent sustained, purposeful activity in a landscape that prehistoric communities knew and used with some intimacy.
