Rye Castle museum
Nobody is quite sure when Ypres Tower was built. It may have been part of a royal castle built sometime between 1230 and 1250, during the reign of Henry III. Normandy had been lost and Henry feared more attacks by the French. Certainly, in 1249, he ordered the Constable of the Cinque Ports, Peter Savoy, to build a castle at Rye but there is now some doubt whether it was ever erected.
It is now thought more likely that it was built at the same time as the town wall and gates, during the reign of Edward III or Richard II in the late 14th century. Its architecture is of that period, and some details of its construction are similar to those of the Landgate; in fact, the Tower was incorporated into the town wall.
