NHER 61104 (Cropmark and Earthwork record) - Probable post-medieval or modern plantation bank on Cranwich Heath

October 2014. Breaking New Ground field visit. HA 31.
A subtle linear bank. Aligned west-northwest by east-southeast, about 100m long and up to 7m wide.
It is not on the line of a feature shown on (S1).

The undated linear bank described above is visible as an earthwork on visualised lidar data (S2). As related above, it is not depicted on readily available historical maps, such as the Ordnance Survey First Edition 6 inch (S1). It does, however, follow the same orientation as a field boundary shown to the north on that map, and it also corresponds with the edge of a plantation on mid-1940s aerial photographs (S3). This suggests that it is a field or plantation boundary, of post-medieval and/or modern date. As the lidar survey was flown relatively recently (2015), it is probable that the earthwork still survives.
The mapped extent of this linear bank has been refined [1].
