This medieval walled city is compact and fun to walk through. In sight of the English Channel, it has interesting shops, cobblestone streets, buildings dating to the 15th century and Henry James' home, Lamb House. Outside of town on the beach lies Henry VIII's Camber Castle (head there on foot for a good walk). You might find Rye a bit touristy. If so, opt for Winchelsea, a planned 13th-century town. 50 mi/80 km southeast of London.
