A spectacular island
At one end of the Isla Santa, opposite the Priory, there is a small island, which is accessible by boat or on foot (only when the tide is very empty and for a very short time because you take the risk of getting trapped). This island was called San Curthbert by an Anglo-Saxon saint, patron of Northumberland. Since he retreated there to pray daily, he built a cross, that produces spectacular effects when the sun aligns with it that is hard to define. This makes giving messes on the beach, looking at the island and the cross with the sunset, quite a different experience. This saint, whose remains (after having opened the grave 3 times) are claimed uncorrupted, is considered one of the most miraculous of the history of the UK, so many people just go to touch his cross.
