When construction work began on the N5 Ballaghaderreen to Scramoge Road Project in County Roscommon, excavations at Killeen revealed a cluster of four pits lying to the east and north-east of a pre-existing enclosure. None of them are large, none are spectacular, and that is precisely what makes them interesting. They are the quiet, functional debris of an agricultural past, the kind of evidence that rarely survives above ground but persists, stubbornly, in the soil.

Two of the four pits appear to have served as processing features for cereal grain. The southernmost, irregular in plan and just 1.5 metres long, contained charcoal, burnt clay, burnt bone, and an abundance of charred plant macrofossils, the carbonised remains of seeds and other organic plant material. The pattern of in-situ burning suggested the pit was used to dry, cook, or otherwise process grain, a task familiar from comparable sites across early medieval Ireland, where small pits and hearths near enclosures often indicate domestic food production. A third pit, found roughly 2.8 metres to its north-east and shallower still, produced a similar assemblage: black clayey silt, heat-oxidised material, ash, burnt bone, and again abundant charred plant macrofossils pointing to the same kind of activity. The remaining two pits told a different story. One, subrectangular and sitting about 9 metres north-east of the first, contained only compacted brownish-red silty clay with faint traces of charcoal; the other, a further 22.5 metres to the north, yielded nothing of interpretive significance at all. Both were read as extraction pits, dug simply to remove soil or stone, perhaps for use elsewhere on the site.

What the excavation caught, in other words, was the unremarkable rhythm of daily life beside an enclosure: some pits for processing food, some for quarrying raw material, the whole small complex sitting quietly in the Roscommon landscape until a road project brought it briefly back into view. Also uncovered nearby were a ring-ditch, a set of linear features, and a further series of pits, suggesting this corner of Killeen was more intensively used in the past than its present surface gives any reason to suspect.
