When Bord Gáis Éireann's Pipeline to the West was being laid through Milltown North townland in County Limerick, topsoil-stripping exposed the disturbed remains of a fulacht fiadh, one of the most common prehistoric monument types in Ireland. A fulacht fiadh is essentially a cooking site, typically comprising a mound of fire-cracked stone, a hearth, and a water-filled trough into which heated stones were dropped to bring the water to the boil. They are found in their thousands across the Irish landscape, often near water, and date mostly to the Bronze Age, though their precise function has been debated by archaeologists for decades, with some arguing they served as brewing vessels, saunas, or textile-processing sites as much as cooking facilities.

The excavation was carried out by Brian Halpin under licence reference 02E0643. What he found was a site already considerably damaged by centuries of farming. The characteristic mound of burnt stone that would normally signal a fulacht fiadh from the surface had been ploughed away, with only faint traces of burnt material surviving in the excavation baulk to the south. What remained were the cut features beneath: a sub-oval trough measuring 2.3 metres east to west and 1.86 metres across, with gently sloping sides, a flat unlined base, and a maximum depth of 0.36 metres. Its fills were exactly what one would expect, layers of charcoal-rich sediment packed with heat-shattered stones, the physical residue of repeated heating and quenching over what may have been a very long period of use. Several irregular pits across the site held similar material, though their specific function was unclear. Most intriguing was a long, irregular feature running roughly 10 metres north to south through the centre of the site, initially interpreted as a kiln but subsequently identified as a probable irrigation ditch. It was only partially excavated owing to the limits of the dig.

The site is not publicly accessible or marked in any conventional sense; it was recorded during a commercial pipeline excavation and is now largely subsumed beneath the surrounding agricultural landscape. Anyone with a serious interest in fulacht fiadh sites in Munster would do better to consult the excavations.ie database, where Halpin's report is recorded, or to seek out better-preserved examples at sites where the mound remains intact. What Milltown North offers, at least on the page, is a clear illustration of how much a monument can lose to the plough while still yielding coherent information below ground.
