Before 2002, this particular corner of Tullerboy townland left no mark on any historic map or aerial photograph. The site simply did not exist in the record until construction crews working on Bord Gáis Éireann's Pipeline to the West broke ground and found what lay beneath.

A fulacht fia, for those unfamiliar with the term, is a type of prehistoric outdoor cooking site, typically associated with the burning of stones to heat water in a trough or pit. They are among the most commonly found prehistoric monument types in Ireland, yet they remain poorly understood in terms of their precise function and social context. This example in Tullerboy, catalogued as part of a cluster of four related sites (LI031-217 through 220) within a roughly 600-metre stretch, was excavated and documented as part of research published by Grogan and colleagues in 2007. The site measured 11.6 metres north to south and 7.8 metres east to west, and comprised seven larger pits along with numerous smaller ones. Most were shallow depressions in the subsoil, filled with charcoal mixed with clay, and parts of the surface were covered with a thin spread of burnt stone and charcoal. The most telling feature was a sub-oval pit, roughly 1.8 by 1.3 metres, whose base held a series of concentric stake-holes. Andrew Halpin, writing in 2004, suggested these stakes may have supported a rack above a roasting pit, or alternatively retained a wooden trough used in the heating process.

The site lies on flat agricultural land, approximately 314 metres east-northeast of Castle Ievers and 315 metres southwest of the boundary with the townland of Drombeg. Access to this kind of subsurface archaeology is, by its nature, no longer visible at ground level; the excavation was carried out during pipeline construction and the land has since returned to working farmland. Its interest lies less in what a visitor might see today than in what the pipeline inadvertently brought to light, a cluster of prehistoric activity that had persisted, undetected, beneath ordinary Limerick pasture for thousands of years.
