A section of linear earthwork bank is visible on 1945 aerial photography (S1), running for approximately 5km east to west, between TF 801 444 and TF 848 452. A further 2km section of bank running north to south between TF 835 451 and TF 835 434 can also be seen. The feature is also in evidence on 1946 aerial photography (S2 and S3). Most of the bank feature is depicted on an 1825 enclosure map (S4), with the exception of the far eastern end, and the far southern end of the north to south section. The bank is similarly shown, although slightly less accurately on Bryant's map of 1826 (S5). The bank also appears on 1st and 2nd edition OS maps (S6 and S7), although again, its easternmost end is not shown. The bank forms a boundary between the coastal salt marsh and areas of reclaimed/cultivated land. The feature is therefore a form of sea defence, protecting the land south of the bank. The same is true of the north to south section of the bank, which would have beeen protecting land to the west from the channels coming inland from the sea. The defences are post medieval in date, as they were being depicted on maps by at least 1825.

The eastern most sections of bank, from TF 83250 4520, are now a separate site, recorded as NHER 26666, as the map evidence of the 1822 plan of the Burnham Salt Marshes (S8) indicates that these banks are earlier than the main stretch of bank.

A row of forty posts aligned east to west was located between TF 81677 45181 and TF 81755 45168. It was seen in a saltmarsh channel, just to the north side of a modern sea bank. It is probably part of the internal structure for an earlier bank, possibly one located here and illustrated in maps dating to 1822 and 1825 (S9).
Numerous upright timber posts and large patches of horizontally laid wattling were recorded eroding out of the bank of a saltmarsh channel between TF 81835 45161 and TF 81933 45139. Located just south of the modern sea bank, the timbers probably form part of the internal structure of an earlier sea bank. They could be part of the bank visible on maps dating to 1822 and 1825 (S9) and located at the site.
