This report presents the final results of archaeological investigations carried out on behalf of Kildare County Council and the National Roads Authority 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 carried out under National Monuments Section Registration Number E2597 in the townland of Moyle Big, Co. Carlow. The Minister for the Environment, Heritage and Local Government, following consultation with the National Museum of Ireland, directed that Joanne Hughes of Headland Archaeology Ltd should proceed with archaeological resolution. This report was later compiled and written by Tara Doyle of Headland Archaeology Ltd. Archaeological testing carried out under N9/N10 Kilcullen to Waterford Scheme: Kilcullen to Powerstown (A021/039), Archaeological Services Contract, Test Excavations Contract 3, Prumplestown to Powerstown under Ministerial Direction Number A021/039 on this site between 9 and 10 August 2005 identified a pit and a double pit associated with metalworking debris. Full archaeological resolution was conducted on this site between the 18 and 26 April 2006. The site comprised of two separate areas, A and B. Two small pits with burning in situ and five pits of various size were identified and excavated in area A. Area B revealed a further two small pits with burning in situ and three pits. Both areas contained modern agricultural activities including field drains, a field boundary, large rubbish pit with plastic inclusions and plough furrows. A natural deposit of peat had filled many natural depressions and stone sockets in both Area A and Area B, all these were excavated and proven to be non archaeological. The crew on this site consisted of 1 Director, 1 Deputy Site manager, 1 Supervisor, between 8 and 10 Site Assistants and between 4 and 6 General Operatives. Following this, archaeological monitoring of topsoil removal by the main contractor Ascon Ltd. took place in July and August 2006 by Angus Stephenson (2007), in areas which had previously been inaccessible 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 (Stephenson 2007). Monitoring area 7 was associated with this site (E2597). Two features were identified during the monitoring phase close to site E2597. Archaeological excavation revealed a large pit located to the northeast of area B with a further small pit located to the east. No archaeological features were identified close to Area A.
