Rebuilt on a shingle bank by Henry VIII to guard the port of Rye. During the civil war the height of the walls and towers were reduced and filled to make it undefendable. The heavy canon were removed to defend Rye and prevent the town falling into royalist hands, as it was feared that the port could be used to land sympathetic Catholic troops. It is now more than a mile inland on the edge of the nature reserve that covers this stretch of coast. About a three mile walk from the free car park by the harbour.
