As you climb the pathway to the castle, look out for the heart-shaped stone amongst the cobbles. Legend has it that it belonged to Cormoran the Giant who, myth has it, built the impressive castle atop St Michael’s Mount but made a nuisance of himself by wading ashore every night to take children and cattle for his supper. Jack, a local boy, crept over to the island and dug a large ‘giant-catching pit’ which Cormoran fell into and disappeared with only his stone heart left. If you are quiet you can still hear the beat of the Giant’s unhappy heart.
