The one at Ballinrea in County Cork is a quiet example of a type that continues to puzzle archaeologists. A fulacht fia typically survives as a low, horseshoe-shaped mound of heat-shattered stone, usually dark and crumbly from repeated burning, situated close to a water source. The prevailing theory holds that these sites were used for cooking, most likely by heating stones in a fire and then dropping them into a water-filled trough to bring it to the boil. Bronze Age in date, broadly speaking, though some examples span a wider range, they appear across lowland bogs and river margins with a regularity that suggests they were once an ordinary, functional part of daily or seasonal life rather than anything ceremonial.

The Ballinrea site sits within a landscape of Cork that has accumulated archaeological interest quietly over time. Ballinrea itself lies in the southern part of the county, and the presence of a fulacht fia there fits a wider pattern of Bronze Age activity across Munster, where these monuments cluster in particularly high densities compared to much of the rest of Europe. The shattered stone middens they leave behind are in some ways their own best record, since the fracture patterns of the burnt stone preserve evidence of sustained, repeated use across what may have been generations. Without more detailed excavation data for this specific site, however, the finer points of its history remain unresolved.
