Felixstowe owes its existence to the 19th-century fashion for seaside holidays when the gentry and businessmen chose to build their summer residences in the parishes of Walton and Felixstowe. In earlier centuries Walton had been the more significant settlement, with a manor and a castle. Even the later fort guarding the Suffolk side of Harwich harbour was often considered to be part of Essex. When the Dutch landed on the Common in 1667 and were defeated by Landguard Fort's garrison, all England heard of the place and King Charles II himself paid them a visit.
