When the N11 improvement works passed through Coolbeg in County Wicklow, archaeologists uncovered a modest but telling cluster of features: two small, shallow burnt spreads sitting close together in the west of a site, an irregularly cut pit with a single fill, a possible post-hole near the centre, and an east-west-aligned field drain to the north. Taken together, these fragments are easy to overlook, but they represent the kind of low-key prehistoric activity that rarely survives long enough to be noticed.

Burnt spreads of this type are generally associated with fulachta fiadh, a term used for the scorched mounds and troughs found widely across Ireland, usually linked to the heating of water by dropping fire-cracked stones into a trough or pit. The two spreads here were uncovered during excavation by Goorik Dehaene as part of the N11 road improvement scheme, under excavation reference E3245. The pit, with its single fill and irregular cut, is consistent with the kind of ephemeral working hollow left behind by repeated short-term use rather than any permanent structure. The possible post-hole adds a faint suggestion that something, perhaps a simple shelter or frame, once stood nearby, though the evidence stops well short of certainty.
