Scottish Power Renewables Site 26, Martlesham, Suffolk. Post- Excavation Assessment and Updated Project Design

Between 18th and 20th July 2017, Archaeological Solutions Ltd (AS) carried out an archaeological excavation at Site 26, to the northeast of Martlesham, Suffolk, as part of the East Anglia ONE Offshore Windfarm (Onshore Works), Suffolk. The excavation encountered a small number of short ditches oriented north-south and approximately parallel to a small indentation adjacent to the west, of the northern edge of the Martlesham Creek floodplain. Within this lower-lying indentation, a localised humic-rich alluvial deposits, 0.40m thick, was recorded and interpreted as the northern edge of floodplain deposits; a 2m x 2m test pit hand excavated into the alluvial did not recover any finds, and no charred plant remains were found in an environmental sample. The date of the alluvium is unknown but considered most likely to be no earlier than the medieval period. One of the short ditches contained three sherds of medieval pottery (11-13th century). An approximately linear cluster of postholes, aligned southwest-northeast, did not contain any finds but based on their distinct appearance and mixed character of their fills, are probably post-medieval or modern in date. The sparse archaeological remains at Site 26 probably relate to land boundaries along the northern edge of the Martlesham Creek floodplain, and on the periphery of a denser area of medieval occupation and activity centred on the site of Creeks Farm (WBG 007; EA1 Site 27), c.200m to the east.
