Polperro, a thirteenth-century fishing village, nestles in a rocky valley 15 miles south-west of Plymouth. The harbour remains very much as it was in times past, with the addition of a harbour wall and huge gates to prevent flooding. The harbour is still a hive of activity, with the daily coming and going of working fishing boats: the harbour is self-supporting. Its history - and Polperro's - is told in the fascinating harbourside museum.
