It measures twenty-four metres long, eighteen metres wide, and less than a metre high, an unremarkable hump of earth to most eyes, yet it is one of the most recognisable monument types in the Irish archaeological landscape.

This is a fulacht fia, a term used to describe the horseshoe-shaped or irregular mounds of burnt stone that appear in their thousands across Ireland, dating predominantly from the Bronze Age. The working theory, supported by experimental archaeology, is that they functioned as outdoor cooking sites. A trough, typically cut into the ground nearby and sometimes lined with timber or stone, would be filled with water. Stones heated in a fire were then dropped into the trough to bring the water to a boil, after which meat wrapped in straw could be submerged and cooked. The cracked, heat-spent stones were raked aside after each use, and over generations of repeated activity they accumulated into exactly the kind of irregular, scorched mound visible at Pollardstown. The proximity to a water source is entirely typical; fulachta fiadh are almost always found close to streams, rivers, or boggy ground, where a reliable water supply was at hand. The example here, sitting in open pasture on what is now farmland in north Cork, conforms to this pattern faithfully.
