The earthwork bank of a former post medieval counter wall, part of the flood defences extending c. 1800m south-east through Higham Marshes from the coastal sea defences at Higham Saltings. East of Beckley Hill the bank changes direction, extending north into the marshes enclosing an area to the north-west of Church Street, curving around and back to a point where the ground rises to the immediate east of Church Street, east of the site of the former Benedictine Priory (another 1540m in length). This bank follows a meandering course, possibly dicated by existing drainage ditches in the marsh. Most is still extant, though parts at the southern end are only visible as slight banks to the east of Beckerly Hill. The banks are present on an 1812 map of the area, but are not present on earlier maps. This embankment was mapped from aerial photographs as part of the English Hertiage: Hoo Peninsula Landscape project.
