It is easy to mistake for nothing in particular, just a slight rise in boggy terrain, but the horseshoe shape and the scorched, fire-cracked stone packed into it mark it out as a fulacht fia, one of the most numerous yet least understood monument types in the Irish landscape.

A fulacht fia is, in its simplest form, a Bronze Age cooking site. The typical arrangement involved a trough dug into the ground, filled with water, and then heated by dropping stones that had been fired in an adjacent hearth. The shattered, heat-crazed stones were raked out and discarded nearby, building up over repeated use into the characteristic horseshoe-shaped mound that survives today. The example at Gooseberryhill measures 5.7 metres long and 6.3 metres wide, though it stands only 0.3 metres high, worn down by time and the softness of the ground beneath it. Its opening, about 1.7 metres across, faces east-southeast. What makes the site a little more arresting is the proximity of a second fulacht fia, recorded just one metre to the northeast. Whether the two were used at the same time or represent successive episodes of activity at the same damp hollow is not known, but their closeness suggests this patch of marshy ground was returned to, possibly across generations.
