A large bank is visible as an intermittent earthwork on 1940s RAF vertical aerial photography [1]. The bank is c.10m wide and visible intermittently running for nearly 1.5km; seven sections of bank are visible in total. It follows a sinuous WNW-ESE course for the first 500m, then turns and runs c.W-E for the next 400m, then turns again and follows a NW-SE aligned course for the remainder of its length. At the eastern end of the WNW-ESE section, the feature is visible as a double parallel bank. The bank does not appear to be a part of the field system shown in this area on historic Ordnance Survey mapping [2]. It is likely to be of medieval or earlier post-medieval date and may be a flood bank or related to the reclamation of land from the Wantsum Channel during these periods. Another linear feature with a similar alignment lies 100m north of this bank and may be associated, see Related Monuments.

The bank appears to have been plough-levelled by the 1960s as Ordnance Survey vertical aerial photographs of this date show it as a cropmark [3].

A transcription of the features recorded from aerial photography exists within a GIS layer held by this HER [4].
