A fulacht fia is a Bronze Age cooking site, typically comprising a mound of fire-cracked stones beside a trough, where water was heated by dropping in stones that had been heated in a fire. They are found in their thousands across Ireland, often close to water, and the one at Bofeenaun fits the pattern almost exactly, situated right at the lakeshore, with a second example of the same type recorded just 75 metres to the north-east.

This particular site was discovered in 1992, when the Irish Archaeological Wetland Unit carried out a survey of archaeological monuments in and around Lough More. By the time it was recorded, fluctuations in lake levels had already done considerable damage, and what remained was a thin layer of burnt stone measuring 7.5 metres long and just 1 metre wide. That modest strip of scorched and fractured material is the residue of repeated episodes of heating, cracking, and discarding, the physical trace of a process carried out over what may have been centuries. The proximity of a second fulacht fia so close by raises questions about how this stretch of shoreline was used, and by how many people, across the Bronze Age.
