Such shingle banks, which are horseshoes and 60,000 nails. a common feature of the Sussex Gunfounding gave Sussex its coastline, are created by reputation.

The waterfront, Lewes Seaford declined as a port in the 14th and 15th centuries due to silting up of the river’s mouth which had made it inaccessible to the large ships being built at that time. In 1539 a man-made cut was made to take the river directly to the sea, where the new exit was appropriately named Newhaven. The Ouse from Lewes to its source was known as the Middewinde, the last evidence for this name being up to 50 km inland. The Upper lost earlier this century when Ouse Navigation finally extended Midwyn Bridge was re-named some 35 km and 18 locks above Lindfield Bridge.
