It is what archaeologists call a fulacht fia, a type of prehistoric cooking site found in enormous numbers across Ireland, typically dated to the Bronze Age. The usual interpretation is that stones were heated in a fire, then dropped into a water-filled trough to bring it to the boil, with the cracked and blackened stones discarded into a mound nearby. Over time, these mounds of fire-damaged material accumulate into exactly the kind of low, horseshoe-shaped rise visible at sites like this one.

What makes this particular mound worth noting is its proximity to another fulacht fia, recorded separately, lying only about thirty metres to the north. Seán P. Ó Ríordáin, one of the foremost Irish archaeologists of the twentieth century, noted both sites in 1937. The pairing is not unique in Irish archaeology, but it is far from routine. Whether the two sites were used simultaneously, sequentially, or by entirely different communities at different points in prehistory is something the surviving evidence does not settle. What the proximity does suggest is that this corner of Cork held some repeated or sustained significance for the people who worked and cooked here, perhaps over a very long span of time.
