It measures roughly seven and a half metres long, six and a half metres wide, and only twenty centimetres high, the kind of subtle rise that most walkers would pass without a second glance. Yet this unassuming hump is a fulacht fia, a type of prehistoric cooking or industrial site found in considerable numbers across Ireland, and it is not alone: a second example of the same kind lies around ninety metres to the south-southwest.

Fulachtaí fia, the plural form, are among the most common archaeological monuments in the Irish landscape. The typical interpretation is that they functioned as outdoor cooking sites, where stones were heated in a fire and then dropped into a water-filled trough to bring it to the boil. The characteristic horseshoe-shaped mound that results is composed of the shattered, fire-cracked stones discarded after each use, which accumulate over repeated episodes into exactly the kind of low, spreading heap visible here. The site at Curragh was most probably the one recorded by a researcher named Bowman in 1934, who noted a fulacht fia on land then belonging to a D. Nugent. The pairing of two such sites in close proximity, less than a hundred metres apart, is itself of interest; clusters like this suggest repeated or sustained activity in a particular area, though the relationship between the two monuments, whether they were in use simultaneously or at different periods, remains unknown.
