NHER 27020 (Cropmark and Earthwork record) - Post medieval sea defences

February 2001. Norfolk NMP.
Two sections of bank are visible as earthworks on 1946 aerial photography (S1), between TF 8462 4499 and TF 8451 4450. They are quite linear and would appear to be man-made. Given the location of the banks and the number of other bank features in this area, it seems likely that these banks may be the remnants of some kind of sea/flood defence or land reclamation effort. The banks may well be post medieval in date, as they are not so well defined or crisp as features NHER 26670 or 27031, although this may also be caused by the failure of these defences and thus erosion of the banks. These features are most likely to be remnants of a sea defence system of modern or post medieval date.
These banks are marked on the 1822 map of the Burnham salt marshes (S2) so are at least this date, probably quite early, as they already seem to be in fragmentary form at this date.
