These are the low, horseshoe-shaped mounds, typically dark with charred and fire-cracked stone, that appear in their thousands across Ireland, usually in low-lying or marshy ground. The standard interpretation is that they were Bronze Age cooking sites, where water in a trough was brought to the boil by dropping heated stones into it, though some researchers have proposed alternative uses ranging from textile dyeing to brewing. Whatever their precise function, they speak to a routine, repeated activity, something practical and communal, carried out over generations in the same spot.

The fulacht fia as a monument type dates broadly to the Bronze Age, roughly 2000 to 500 BC, though some have earlier or later associations. The characteristic mound is formed not from deliberate construction but from the gradual accumulation of discarded material, stone that had been heated, cracked by thermal shock, and then raked out of the trough to make way for the next batch. Over centuries, this debris built up into the low crescentic form that field surveyors still recognise today. Clare has a considerable number of recorded examples, as the county's boggy terrain and numerous water sources provided exactly the conditions these sites seem to require. Sranagalloon, a quiet rural townland, is one of many such places in the county where the Bronze Age left a mark that is easy to walk past without knowing what you are looking at.
