These low, kidney-shaped mounds of fire-cracked stone and charcoal-blackened soil appear in their thousands across Ireland, and for much of the twentieth century they were considered little more than agricultural nuisances. What they actually represent is a sustained and organised use of heated stone, most likely for cooking or bathing, in which water was boiled by dropping fire-heated rocks into a trough or pit, the spent stones then raked aside into the characteristic spreading heap.

The Scratenagh site was excavated by archaeologist Goorik Dehaene, whose work uncovered not only the mound itself but an associated hearth and a series of pits, the kind of cluster that suggests repeated activity over time rather than a single episode. Radiocarbon dating placed the site firmly in the middle Bronze Age, a period broadly spanning the centuries around 1500 to 1000 BC, when this corner of Wicklow would have looked very different, the landscape more open, the communities small and dispersed across a countryside already shaped by generations of farming and metalworking. The hearth and pits give the site a domestic intimacy; this was a place where people returned, built fires, heated stones, and went about whatever practical work the installation was built to support.
