In the year 635, King Oswald gave the Holy Island of Lindisfarne to St. Aidan to establish his monastery, and ever since the island has been a place of pilgrimage. The causeway road was not constructed until 1954 and until then the vertical poles were the only indicators of the safe route between the mainland and the island. The sight of the poles stretching across the sand and mud is one of the most iconic views in Northumberland and to walk the route and follow in the footsteps of our medieval ancestors is a wonderful experience.
