What was uncovered at Keeltane in County Cork belongs to a class of site known as a fulacht fia, a type of ancient cooking or processing place found in enormous numbers across Ireland, typically dating to the Bronze Age. The usual interpretation is that stones were heated in a fire and then dropped into a water-filled trough to bring it to the boil; over repeated use, the cracked and discarded stones accumulated into the low, often horseshoe-shaped mounds that survive to this day.

The Keeltane material came to light in 2003, not through a dedicated excavation but during archaeological monitoring of the construction route for the Charleville-Newmarket 110kV electricity line. That kind of watching brief, where an archaeologist accompanies groundworks in areas of potential sensitivity, regularly turns up sites that were never previously recorded. Here it exposed the characteristic deposits without fully excavating them, and the material has remained undisturbed since. What makes the location quietly interesting is its immediate surroundings. A holy well sits just to the east of the burnt mound, and approximately thirty metres to the south lie the remains of a possible church and associated graveyard. The clustering of these features, a prehistoric cooking site, a sacred spring, and what may be an early Christian ecclesiastical enclosure, within such a compact area suggests that this particular patch of ground accumulated layers of significance across a very long stretch of time, each generation finding its own reasons to mark or use the spot.
