This final report presents the results of archaeological investigations carried out on behalf of Kildare County Council as part of Archaeological Services Contract No. 4 ? Resolution, Prumplestown to Powerstown, prior to the commencement of construction on this section of the N9/N10 Kilcullen to Waterford Scheme: Kilcullen to Powerstown. The work was undertaken under National Monuments Section Registration Number E2588, in the Townland of Ballybar Upper, Co. Carlow. The Minister for the Environment, Heritage and Local Government, following consultation with the National Museum of Ireland, directed that Áine Richardson of Headland Archaeology Ltd should proceed with archaeological resolution. The report was written by Gerry Breen who supervised work at the site and T.J. O’ Connell (Deputy Site Manager) as Ms Richardson was no longer employed by Headland Archaeology Ltd during the post?excavation phase of the project. Archaeological testing carried out under the N9/N10 Kilcullen to Waterford Scheme: Kilcullen to Powerstown; Archaeological Services Contract No. 3 – Test Excavations, Prumplestown to Powerstown under Ministerial Direction Number A021/030 on this site on the 27 – 29 August 2005 identified four pits, two of which were interpreted as cremation burials of a possible prehistoric date (Long 2005). Full archaeological resolution was conducted on this site from 9 March to 28 April 2006. This revealed two cremation burials, early medieval features, a high medieval, inhumation burial in a ditch, post medieval field boundary ditches and a number of miscellaneous features that could not be ascribed to any of the particular phases of the sites use. A programme for monitoring of topsoil stripping took place in July and August 2006, in areas that had previously been inaccessible for logistical reasons or were deemed to have high archaeological potential. In total, 16 monitoring areas were designated. The majority of these areas were concerned with the widening of existing roads and included Monitoring Areas 1, 2, 3, 4, 5, 6, 8, 9, 10, 11, 13, 14, 15. Monitoring Area 7 involved several fields and surrounded several sites (E2593, E2596, E2595, E2597, and E2598). This area was considered as having high archaeological potential as a castle site (RMP CW007?051) was situated directly south of site E2595. Monitoring Area 12 involved the removal of a corner of Burton Hall estate and included the cutting down of several trees and the demolition of a stone wall. Monitoring Area 16 was a waterlogged strip of land adjacent to the Dublin to Waterford railway line. The findings from the 16 Monitoring Areas were compiled into one report. One such site was located in proximity to the site at Ballybar Upper. This was Monitoring Area 2. One shallow pit was excavated in the southern part of the Monitoring Area. No finds were recovered (Appendix 13) (Stephenson 2007) (Figure 1).
