The Rhee Wall is a former watercourse in Romney Marsh in Kent, England.
[1][2] It consists of two parallel earth banks, from 50 to 100 metres apart, the ground between being raised above the marsh on either side.
After the South England flood of February 1287, the harbour at New Romney was completely blocked.
The Rhee Wall has not contained water since medieval times.
In the present day, the B2080 road follows the route of the Rhee Wall from Appledore south-east to Brenzett; the route continues south-east to New Romney as part of the A259 road.
