As one of the two "Antient Townes" (Winchelsea being the other), Rye was to become a limb of the Cinque Ports Confederation by 1189, and subsequently a full member. The protection of the town as one of the Cinque Ports was very important, due to the commerce that trading brought. One of the oldest buildings in Rye is Ypres Tower, which was built in 1249 as "Baddings Tower", to defend the town from the French, and was later named after its owner, John de Ypres. It is now part of the Rye Museum.
