NHER 69648 (Monument record) - Possible area of medieval or later settlement, post-medieval or earlier field boundaries and undated possible square enclosure

October 2022-February 2023. Geophysical Survey.
Magnetometer survey of part of large potential development site (Area 3).
By far the most notable responses are a relatively dense cluster of magnetically strong linear and discrete anomalies at the northern edge of the site, adjacent to the Aylsham Road. The rectilinear arrangement of the former suggests they represent ditches forming at least two enclosures, while the discrete anomalies are potentially associated pit-type features. They are similar to a more extensive band of similar responses seen at the southern end of the field to the north-west (NHER 69647) and potentially represent another area of medieval or later roadside settlement. Also of potential archaeological interest is a rectilinear response at TG 2713 2986 that possibly represents a small square enclosure (the dimensions of which would be approximately 31m x 31m).
Various linear anomalies were recorded across the remainder of the site, the most distinct of which are an interconnecting group of north-north-east to south-south-west and west-north-west to east-south-east responses that clearly correspond with former field boundaries shown on the North Walsham tithe map (S1). A north-north-east to south-south-west aligned linear anomaly extending southwards from the possible settlement remains at the north edge of the site potentially probably represents an earlier element of this field system.
Various fragmentary, weak linear anomalies recorded in the northern part of the site are regarded as being of uncertain origin, although they may also represent archaeologically-significant remains. The same is true for a number of relatively weak discrete anomalies, including a more pronounced cluster at TG 2730 2993.
Areas of magnetic disturbance at the margins of the field and scattered dipolar 'spikes' were probably caused by ferrous material on or close to the surface – most likely modern debris.
Two linear dipolar trends (one aligned north-west to south-east and the other north-east to south-west) are likely to represent modern services.
