In splendid isolation
Towering more than 100ft over the North Sea off Northumberland’s coast, getting to Lindisfarne Castle can be an adventure in itself. Cut off by the tide twice a day, visitors must cross the causeway to tiny Holy Island at the right time before tackling that steep climb up to the castle. Dramatically situated high on a volcanic ridge, there’s been a stone fort here since the reign of Elizabeth I.
