The archaeological site at Ballinacarrig was located within the lands acquired for construction of the N80 Ballinacarrig Roundabout scheme, Co. Carlow. Part of this area had previously been geophysically surveyed by GSB Prospection (licence no. 04R010) as part of the archaeological assessment of the proposed Carlow Outer Relief Road (a non-national road project). This gradiometer survey identified a number of anomalies of archaeological potential, however, no clear patterns were evident in the data. The remains described in this report were revealed during test excavation in July 2015 under licence 12E0363 and was excavated under the direction of Kate Taylor of TVAS (Ireland) Ltd in August-October 2015 under the same licence. The excavation encompassed an area of 1,825m² and was situated in a ploughed field to the west of the N80 Carlow to Enniscorthy road and north of a local road (L1028). The excavation was located north of a church and graveyard (SMR no. CW007-025). The excavation revealed four phases of activity at the site. The earliest being an Iron Age annular ring-ditch, the second part of an early medieval enclosure and kilns, thirdly a late medieval kiln and boundary ditches, and lastly a late medieval to early post-medieval pit, and post-medieval agricultural activity. Cremated human bone in the fill of the ring-ditch represent the remains of a minimum of one adult individual. The cremated bone was associated with beads made of glass, bone and stone, and a possible copper alloy pin shaft. A segment of curving ditch is interpreted as part of an early medieval enclosure, part of a lignite bangle was found in the basal fill. Two unlined early medieval kilns were identified, the charred cereal remains from their fills were principally oats, wheat was also present. A stone-lined keyhole-shaped kiln was also found, it is dated to the late medieval period. Analysis of the charred plant remains revealed that wheat was the principal cereal crop, evidence for peas and legumes was also identified. The late medieval pottery assemblage comprised Leinster Cooking Ware and Kilkenny-ware. The archaeological features within the site were fully excavated, although the enclosure ditch and several medieval ditches continued outside the lands acquired for road construction.
