Beneath the turf lies a spread of burnt and shattered stone, running about fifteen metres north to south and seven metres east to west, the physical remains of a fulacht fia. These are among the most common prehistoric monuments in Ireland, essentially outdoor cooking sites where stones were repeatedly heated in a fire, dropped into a water-filled trough until the water boiled, and used to cook meat. The process fractures the stone, and it is the accumulated debris of those discarded, heat-cracked fragments that forms the characteristic horseshoe-shaped mound seen at sites like this one across the Irish landscape.

The Woodpark example was first recorded by Bowman in 1934, placing it within a long tradition of antiquarian observation before more systematic archaeological survey took over. Most fulachtaí fia date to the Bronze Age, roughly 1500 to 500 BC, though some are earlier or later. Their clustering near streams and boggy ground reflects the practical logic of their construction: a reliable water supply was essential to the whole operation. This one, sitting quietly in pasture with the stream just a short distance off, fits that pattern exactly. The site has not been excavated, so the full extent and condition of the trough or any associated features beneath the spread of burnt material remains unknown.
