NHER 65948 (Monument record) - Post-medieval and potentially earlier field boundary ditches

May 2020-January 2021. Geophysical Survey.
Magnetometer survey of site on proposed route of onshore cable for Norfolk Vanguard and Boreas Offshore Wind Farms (Area 199).
This survey identified several linear responses, including a north-east to south-west aligned anomaly at the eastern edge of the field and an adjoining perpendicular anomaly that was traced into the field to the east (NHER 65947). Although the orientations of these probable field boundary ditches suggests a relationship with the extant field system no corresponding features are shown on the available 19th-century maps. A north-north-east to south-south-west aligned linear anomaly recorded at the western end of the site does though coincide with a former field boundary depicted on the Reepham tithe map (S1).
Although various discrete patches of magnetic enhancement were also recorded these are also thought to be of natural origin.
Scattered dipolar anomalies and an area of magnetic disturbance at the western end of the site were probably caused by ferrous material on or close the surface, most likely modern debris.

October 2020-June 2021. Trial Trenching.
Evaluation of site on proposed route of onshore cable for Norfolk Vanguard and Boreas Offshore Wind Farms (Area F198; Trench 254).
The single trench excavated at this location was placed to coincide with the westernmost of the linear anomalies identified by the preceding geophysical survey – which can be seen to coincide with a former field boundary shown on (S1). A corresponding ditch was encountered but no dating evidence recovered.
