Southwold, Suffolk - Southwold was mentioned in Domesday Book (1086) as a fishing port, and, after the "capricious River Blyth withdrew from Dunwich in 1328, bringing trade to Southwold in the 15th century", it received its town charter from Henry VII in 1489.
Margate. That formerly uncool seaside resort in north-west Kent, has had quite the revamp. It is part of Thanet, which also includes the seaside towns of Ramsgate and Broadstairs, and was recently mentioned in Frommers must-see destinations for 2011. Margate is packed with quirky cafes and vintage shops, and it's also home to the new Turner Contemporary gallery.
