On the North Sea and Channel shores the Southeastern coast of England holds perhaps the record for the number of towns gobbled up during recent--historic--times. The relative level of the sea to the land has varied over the centuries: in the late Roman period, and again from about 1250 onwards. Protective dykes were constructed but were repeatedly destroyed by the sea See (J. A. Steers , 1969 The Sea Coast ). There were periods of accretion that resulted for instance in the creation of the salt marshes of Essex and the Wash. Once flourishing settlements on the eastern coast of England have been completely destroyed some before, some during the Middle Ages (T. Sheppard , Lost Towns of the Yorkshire Coast ( 1912). Ravenser Odd for instance prospered but disappeared under the sea in the 14th century, when major flooding occurred several times, with the worst floods in the 15th century (Peter Brandon and Brian Short , The South East from AD 1000 ( 1990 ).
