A fulacht fia, the term used for a Bronze Age burnt mound typically associated with outdoor cooking or heating water, was identified here not through archaeological excavation or aerial survey, but by the landowner during reclamation work. The site sits on a south-facing slope at the southern end of a north-to-south ridge, and nothing now marks it at ground level.

What makes the find quietly interesting is that it did not arrive alone. A second fulacht fia was recorded under similar circumstances roughly 500 metres to the north-west, also noticed during land reclamation. These sites tend to cluster near water sources, which fits a south-facing slope in reclaimed grassland, and their appearance in pairs is not unusual. Bronze Age communities returned repeatedly to the same kinds of locations, and the two sites at Kilmagar suggest the area saw sustained activity over time rather than a single isolated event. The circumstances of discovery, work on the land rather than a planned dig, is itself typical of how many such sites come to light across Ireland, where the plough or the digger does what fieldwalking surveys cannot.
