NHER 66335 (Monument record) - Undated ditch and probable extraction pit

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 (S1).

November 2021-March 2022. Geophysical Survey.
Magnetometer survey of site on proposed route of Hornsea Project Three offshore wind farm onshore cable (Area 56).
This survey identified no potentially archaeologically-significant responses. Although a number of linear anomalies were recorded all were likely to be the result of recent agricultural activity. Other, more amorphous anomalies were likely natural in origin.
Information from draft report. Final version awaited.

February-June 2022. Trial Trenching.
Evaluation of site on proposed route of Hornsea Project Three offshore wind farm onshore cable (P2TT65; Trenches 635-641).
The seven trenches excavated recorded only a single ditch and a large pit. The ditch was a north-west to south-east aligned feature that produced no dating evidence. The large probable extraction pit was found to contain two small sherds of Early Neolithic pottery but this was most likely residual.
Information from draft report. Final version awaited.
