These are fulachtaí fia, a type of monument found widely across Ireland, typically consisting of a trough, a hearth, and a mound of heat-shattered stone left over from repeated use. The method was simple: stones were heated in a fire and then dropped into a water-filled trough to bring it to the boil, probably for cooking meat. The marshy, stream-fed terrain at Sraghgaddy would have been ideal for this purpose, since a reliable water source was essential to the process.

The first edition Ordnance Survey map records the area as boggy ground with a stream running roughly north-west to south-east. By the time the map was revised around 1900, a railway line had been driven across the landscape in a north-east to south-west direction, cutting through the same ground. It was near this railway that the sites first came to wider attention. Land Project drainage operations in 1959 uncovered fulachtaí fia in the area, as noted by O'Kelly in 1969. Prendergast had already recorded the cluster in 1955, listing at least six sites in Shraghgaddy townland. Despite being registered individually, the separate monuments within this group have not been precisely located on the ground, which means the full character and condition of each site remains unclear.
