Monument record LCS 097 - Post Medieval sea banks.

A long section of sea bank is visible as an earthwork on 1943 (S1) & 1945 (S2) aerial photographs to the east of Leiston chapel. On the whole the bank runs N-S, but there are other attached shorter sections of bank towards the northern end of the main feature. The bank is part of the flood defences in this area, and may well date to the post-medieval period. These sections of sea bank are depicted as earthworks on the OS county series 1st ed 25" map of c1884, which further suggests their post-medieval origin. Also on the 1880s map, a windmill is depicted by a gap in the banks at TM474658 (recorded as LCS 015). There may be a feature visible in this location on the aerial photographs, but it is very small and difficult to be ceratin that it is in fact the windmill, or remains thereof.
