NHER 24977 (Cropmark and Earthwork record) - Site of possible hengiform ring ditch of doubtful archaeological origin

14 September 1981. Cambridge University Committee for Aerial Photography aerial photography (S1).
Possible causewayed ring ditch or mini-henge type feature.

However exercise caution - note the similar natural marks around it.

January 2008. Norfolk NMP.
The possible hengiform monument or ring ditch described above is visible as a cropmark on aerial photographs (S1), centred at TG 2547 1872. Such features are known from elsewhere in Norfolk, where in some cases they might feasibly represent the remains of late Neolithic or Bronze Age funerary and/or ceremonial monuments. Alternatively, such marks are also typical of medieval or post medieval post mill sites. In this case, however, and as suggested above, the archaeological significance of the cropmarks is uncertain, as it appears from the aerial photographs that the background geology of the area is conducive to the formation of curvilinear marks. (Compare NHER 50782, located 277.5m to the northeast.) Any relationship with other cropmarks in the area is unknown.
The ring ditch is distinctly oval in plan, reinforcing the impression that it is a non-archaeological feature. It measures 23.5m long and 19m wide. It is oriented east to west, and has a distinct ‘entrance’ at each short end, defined by swollen termini to the ditches.

January 2020. Geophysical Survey.
Magnetometer survey of proposed aggregate extraction area.
This survey identified a pair of curving linear anomalies that clearly correspond with these cropmarks. Although the origin of the cropmarks was deemed to be uncertain it is noted that the geophysical anomalies are distinct from the surrounding background texture, making an anthropogenic origin more likely.
See report (S2) and NHER 68260 for further details.
