Between 26th June and 3rd July 2017, Archaeological Solutions Ltd (AS) carried out an archaeological excavation at Site 34, to the northeast of Newbourne, Suffolk, as part of the East Anglia ONE Offshore Windfarm (Onshore Works), Suffolk. The site was designated Site 34 for the purposes of archaeological recording in advance of cable trenching for the East Anglia One project. The excavation encountered a c.20m long arc of the eastern edge of a Bronze Age double-ring ditch monument known from crop marks (Site code: NBN009). The full width of the outer ring ditch was not fully exposed in the excavation, and two sherds of Late Bronze Age/Early Iron Age pottery were found in the upper fill. Abutting the outer, eastern edge of the ring ditch were at least two phases of co-axial field system/enclosure ditches, the fills of which contained a very small quantity of Roman pottery dating to the mid/late 2nd century AD. Skirting the southern edge of the Bronze Age ring ditch were two shallow, e-cut, parallel ditches, one of which contained late medieval pottery (15-16th century); the parallel ditches probably represent a double-ditch boundary/drove way oriented approximately east-east. The alignment and position of the late medieval boundary/droveway suggests that the Bronze Age ring ditch (barrow) monument may have remained a visible landscape feature into the medieval period.
Lloyd-Smith et al. (Tue,) studied this question.
