What appears to a casual eye as a scatter of blackened earth and broken stones is in fact the remnant of a fulacht fia, a type of prehistoric cooking place found in considerable numbers across Ireland. The typical arrangement involved heating stones in a fire and dropping them into a water-filled trough to bring it to the boil, a process that left behind exactly this signature: charcoal, and stones cracked and shattered by repeated thermal stress.

What makes Inchanappa particularly notable is not the presence of one such site but three, all lying within the same field. This example sits roughly twenty to thirty metres north-northwest of a neighbouring fulacht fia, with a third recorded close by as well. The clustering of multiple sites in a single location is a pattern seen elsewhere in Ireland and raises questions about repeated use over generations, or perhaps seasonal gatherings that returned to the same landscape. None of the three sites has been excavated, so the relationship between them remains a matter of inference rather than established fact. They are known primarily from what ploughing has brought to the surface, and their full extent underground is uncertain.
