But yes, erm it, it's partly sediment brought down from inland, it's also the fact that you have offshore of Rye the area of Winchelsea Beach and so-called Rye Harbour which is somewhat detached from the town of Rye, and there's been an enormous accumulation of shingle there, so that the Castle, which was built in, that's Camber Castle which was built in the reign of Henry the Eighth, since that time the shoreline at Winchelsea Beach, as a result of the accumulation of shingle, has moved in excess of one point five kilometres seaward of that point, and so obviously erm Rye is now much further inland than it was at that time.
