A fulacht fia is a type of prehistoric cooking site, typically identified by a horseshoe-shaped mound of fire-cracked stone and charcoal left behind after repeated episodes of water-heating, in which stones were burned and dropped into a water-filled trough to bring it to temperature. Their presence in boggy, low-lying ground is characteristic; the proximity to standing or running water was essential to how they functioned.

The first edition Ordnance Survey map recorded the area as marshy terrain with a stream cutting through it from north-west to south-east, precisely the kind of waterlogged setting that fulacht fia repeatedly favour across the Irish landscape. By the 1900 revision, a railway line running north-east to south-west had cut across the same ground, and it was near this line that the sites first came to light. During Land Project drainage operations in 1959, the fulachta fiadh were uncovered, as noted by O'Kelly in 1969. Prendergast, writing slightly earlier in 1955, had already recorded at least six sites in Sraghgaddy townland, suggesting awareness of the cluster predated their formal exposure. The six sites were assigned individual record numbers but have not been individually located on the ground, meaning their precise positions within the townland remain uncertain.
