NHER 64518 (Monument record) - Potentially Late Bronze Age features and post-medieval former field boundaries

May-June 2009. Geophysical Survey.
Magnetometry survey of proposed development area (Fields 3 and 10).
The only response identified as potentially archaeologically significant was a discrete positive anomaly at the western edge of the site that may represent a soil-filled pit. The other discrete anomalies identified were all thought to be the result of modern debris.
Three adjoining lines of magnetic anomalies almost certainly correspond with the positions of former field boundaries. Two clearly coincide with boundaries marked on the 1846 Hethersett Tithe map (S1), while the third is likely to represent a related boundary that had already been removed by this time. The third boundary was also detected in the field to the east (NHER 64519).
A particularly pronounced north-to-south aligned band of anomalies at the western edge of the site marks the line of a high pressure steel gas pipeline.
Linear anomalies running parallel to the modern boundaries at the northern and southern ends of these fields are interpreted as modern plough headlands.

May 2018. Desk-based Assessment.
Environmental Impact Assessment of the potential impacts of the proposed Hornsea Project Three offshore wind farm on the historic environment. This study incorporated the results of an initial walkover survey and the first phases of geophysical survey.
See relevant chapter of Environmental Statement and associated appendices for further detail (S3).

February-June 2022. Trial Trenching.
Evaluation of site on proposed route of Hornsea Project Three offshore wind farm onshore cable (P3TT28; Trenches 1227-1236).
Ten trenches excavated at the western edge of the site revealed only a small number of linear and discrete features. There was though evidence for at least some limited prehistoric activity at this location with what appeared to be an east-to-west aligned ditch found to contain a small assemblage of Late Bronze Age pottery, along with a number of burnt flints. A single Late Bronze Age pottery sherd was also recovered from an adjacent pair of otherwise undated post-holes approximately 150m to the south.
The only other feature recorded was a north-to-south aligned ditch that appears to have coincided with a former field boundary depicted on the Hethersett Tithe Map (S2).
Information from draft report. Final version awaited.
