Dartmouth Castle sits low on the rocks at the very mouth of the River Dart, so close to the water that waves break just below the walls. The townspeople of Dartmouth began building it in the late 1380s to protect their harbour, and it became one of the first castles in England designed specifically for guns rather than bows. In wartime a great iron chain could be stretched right across the estuary to Kingswear Castle on the far bank, blocking enemy ships from sailing up to the town.
The little church of St Petrock stands beside it, tucked in against the fort, and the whole spot has a snug, tucked-away feel despite its serious job. English Heritage looks after the castle now. You can walk out along the South West Coast Path from Dartmouth, or in the warmer months a small passenger ferry runs down the river from the town quay, which is the nicest way to arrive.
The town of Dartmouth itself, with its steep streets and boats, is worth time. Just beside the castle is the sheltered little swimming spot at Dartmouth Castle Cove, a favourite for a quick dip on a calm day.
