Topsoil-stripping along the route exposed the remains of a fulacht fiadh, the type of prehistoric cooking site found in considerable numbers across Ireland, typically consisting of a mound of fire-cracked stone beside one or more water-filled troughs into which heated stones were dropped to boil the water. What made this particular example quietly interesting was not one trough but two, sitting side by side in the yellow-grey clay subsoil, their presence suggesting a level of activity or organisation slightly beyond the ordinary.

Excavator Brian Halpin recorded the site under reference 02E0526, noting that the double trough measured 7.6 metres along a north-east to south-west axis. Both troughs were roughly equal in size, each cut in a subcircular shape with a deep U-shaped profile, and each contained five fills rich in charcoal and heat-shattered stone, the characteristic debris of repeated high-temperature use. A large piece of charred wood was recovered from the upper edge of the western trough. Beneath the troughs, and pre-dating them, lay an irregular metalled surface, a rough pavement of loosely packed stones covering an area of approximately 6 metres by 4 metres, probably laid in a single episode of activity. The troughs had been cut directly through this earlier surface, implying at least two distinct phases of use at the same spot. South of the troughs, excavators found a small subcircular pit with an undercut profile, likely a storage feature rather than a structural one; it yielded charred hazelnuts, a detail that hints at food preparation or storage beyond simple meat-boiling. The full extent of the site was never established, as part of it lay outside the excavation limit.

Because this site was uncovered during pipeline construction rather than through a designated heritage project, there is no publicly accessible monument or visitor point at Ballymackeamore. The record exists primarily through the excavations.ie database, where Halpin's report can be read in full. For those interested in fulacht fiadh more broadly, the site serves as a useful case study in how infrastructure work continues to produce unexpected archaeological finds, and how even a partially excavated example can carry quite specific information about sequence, function, and the texture of prehistoric daily life.
