Full Description

A stretch of sea bank c 1.75km long can be seen as an earthwork between TM49607403 & TM48877294 on aerial photographs from 1941 (S1) and 1945 (S2). It is slightly fragmented at its southern end. The bank is likely to be a component in the flood defence system in this area and may well date back to the post medieval period, as a number of other similar banks in this area also do. The bank is depicted on the 1st Ed County Series OS 25" map for this area, which dates back to c1884, which further strengthens the case for it being a post-medieval feature. The is another small section of bank, c 100m long, to the north of the longer stretch, which is located on the opposite side of the channel. By comparing it with the depiction on the 1st Ed County Series OS map, it is possible to see that a large proportion of the feature has in fact eroded away.
