Berwick-Upon-Tweed.

Berwick-Upon-Tweed sits where England meets Scotland, its Elizabethan walls having changed hands between the two nations more times than any other border town in Britain. Wander past the ramparts and you'll find a working harbour town with a strong café culture, with cafes tucked along cobbled streets overlooking the Tweed estuary. For an overnight stay, a handful of hotels offer views over the river mouth and North Sea beyond.
