A cathedral city until AD 870, Dunwich was one of England's greatest port towns during the medieval period. Coastal erosion has destroyed its many churches, monasteries and public buildings. After repeated major floods, only fragments of buildings remain for a while on the clifftop. The place still has an atmosphere and a good strip of beach, it's a lesson for anyone concerned about climate change. The outline on the map is roughly based on historical accounts.
