The burnt material sits in waterlogged ground, its full extent never properly determined, which gives the site an unresolved quality that is, in its own way, entirely appropriate to what these features represent.

A fulacht fia is essentially a Bronze Age cooking place, or possibly a site used for brewing, textile processing, or bathing, the exact purpose still debated among archaeologists. The typical arrangement involves a trough dug into boggy ground, filled with water, and heated by dropping fire-cracked stones into it; the discarded, shattered stones gradually accumulate into the low horseshoe-shaped mound that survives today. What makes the Aglish example particularly interesting is that it does not stand alone. It is one of a group of three fulachta fiadh running along the north side of the same stream, suggesting that the location was returned to repeatedly, or that several groups made use of the same reliable water source over an extended period. The clustering of such monuments is not unusual in Ireland, where valley floors and stream margins were clearly preferred ground, but finding three in close proximity along a single watercourse points to sustained activity in this particular corner of Mid Cork.
