This is a fulacht fia, a type of prehistoric cooking site found in enormous numbers across Ireland, typically consisting of a mound of fire-cracked stone accumulated beside a water source or trough. The ground immediately to the north of this example is waterlogged, which is entirely typical; these sites were almost always positioned close to standing or running water, which was heated by dropping stones that had been fired in a nearby hearth directly into a wooden or stone-lined trough.

What makes this particular spot quietly interesting is its proximity to another fulacht fia just ten metres to the east. Whether the two were in use simultaneously or represent activity at different periods is impossible to say from surface evidence alone, but their nearness to one another is suggestive of a landscape that was returned to repeatedly, perhaps over generations, by communities who found this corner of Cork well suited to communal cooking or food processing. Fulachtaí fia, as the plural has it in Irish, date most commonly to the Bronze Age, roughly 1500 to 500 BC, though examples span a much wider range. The characteristic burnt mounds they leave behind are often the only visible trace of daily life from that era, which makes even an unassuming grass-covered spread worth pausing over.
