No earthwork rose above the surface, no crop mark showed on aerial photographs, and the Ordnance Survey maps carried no indication that anything lay beneath the grass. It took the mechanical excavation of a gas pipeline to expose it: a small, bowl-shaped pit, roughly 71 centimetres by 64 centimetres across and 13 centimetres deep, filled with dark grey silty clay, charcoal, and fire-shattered stone. The pit is what archaeologists recognise as a likely remnant of a fulacht fia, a type of Bronze Age cooking or processing site, typically involving a trough of water heated by dropping fire-cracked stones into it until the water boiled. The stone, repeatedly heated and cooled, eventually fractures, and the discarded fragments accumulate in characteristic spreads and mounds around the trough.

The site sits about 520 metres east of Castle Ievers and 250 metres southwest of the townland boundary with Drombeg, in Tullerboy townland. It was one of four prehistoric sites, recorded under references LI031-217 through 220, excavated within a 600-metre stretch during the Bord Gáis Éireann Pipeline to the West project in 2002. The excavation was carried out under licence number 02E0501, and the broader results of the pipeline project were published by Grogan and colleagues in 2007, with Taylor's 2004 assessment suggesting a Bronze Age date for features of this type. No artefacts were recovered from the pit itself, which is not unusual; fulacht fia sites rarely yield objects, their archaeology expressed almost entirely in the burnt stone and charcoal that accumulate from repeated use.

There is nothing to see at the surface today. The site lies on private agricultural land, and the excavation that revealed it will long since have been backfilled as the pipeline works concluded. What makes it worth knowing about is precisely its ordinariness within the extraordinary: a prehistoric site so slight and so thoroughly buried that centuries of farming, mapping, and aerial survey left it undetected. The four sites discovered in close proximity here suggest that this stretch of Limerick countryside saw repeated prehistoric activity, each site quietly preserving its small cargo of cracked stone and ash until a gas pipe happened to pass through.
