The site recorded here is the most disturbed of the group, reduced now to a spread of scorched and shattered stone, but the sheer concentration of similar monuments in such a small area hints at a landscape that was once, in some seasonal or repeated sense, intensively used.

A fulacht fia, sometimes called a burnt mound, is among the most common prehistoric monument types in Ireland. The basic principle involved heating stones in a fire, dropping them into a water-filled trough to bring it to a boil, and using that heat to cook meat or process other materials. The spent stones, cracked and blackened by repeated thermal shock, were piled to the side, forming the characteristic horseshoe-shaped mounds that survive across the Irish countryside. The Gortavehy example has been much disturbed, its original mound shape difficult to read, though the burnt material that defines such sites remains visible across the ground. Its three neighbours lie within a tight radius to the north and north-west, suggesting this corner of mid Cork held some particular draw, whether for water, for grazing, or for communal gathering, over a long stretch of prehistoric time.
