Early Medieval Enclosure Complex (Barnahely)
By far, the standout site from the M28 project is the multi-enclosure complex at Barnahely 2. Three ringforts, two containing souterrains, and a later enclosure and associated cereal-drying kiln were found. Ringforts are defended farmsteads of early mediaeval date. The souterrain (underground passage) within one of the ringforts appears to have utilised an underlying cave system. A large quantity of artefacts was uncovered from the excavation, as well as charred plant remains, animal bone, marine shell, whale bone, and metalworking debris, which, collectively, provide evidence for several crafts, including metalworking, glassworking, leatherworking, comb making, lignite working, woodland harvesting, textile production and more. This suggests that at least one of the ringforts was high status.
