Scottish Power Renewables Site 40, Kirton, Suffolk. Post-Excavation Assessment and Updated Project Design

Site 40, to the north of Kirton, Suffolk, as part of the East Anglia ONE Offshore Windfarm (Onshore Works), Suffolk. The site was designated Site 40 for the purposes of archaeological recording in advance of cable trenching for the East Anglia One project. The excavation encountered one pit cluster in the north of the site comprising three small features containing late Bronze Age/early Iron Age pottery. Broadly contemporaneous with the pit cluster, two parallel ditches oriented southwest-northeast, and containing late Bronze Age/early Iron Age pottery in their fills, crossed the southern area of the site. The two ditches are c.9.5m apart and appear to form a ditched trackway, the southwest projection of which appears to be aligned on the southeast edge of a c.15m diameter ring ditch (KIR052) visible a cropmark in the adjacent field. The northeast projection of the parallel ditches appears also to be towards a second circular cropmark visible on Google Earth (2008) but not yet assigned a HER number. The distance between the two circular cropmarks, and thus the possible full length of the parallel ditches (trackway) recorded in Site 40, is c.350m. This late Bronze Age/early Iron Age trackway/boundary feature recorded at Site 40 is a northern extension of the expansive prehistoric field system, including a similar parallel ditched 'trackway' recorded at Site 39, c.200m to the south.
