This is an incredible place!

Explorica’s description:
“Stop to see Mont-St-Michel, an enormous abbey that seems to rise up out of the water, completely isolated from any connecting land. Perched on an enormous rock just off the Normandy coast, the granite Abbey of Mont-St-Michel actually is linked to the mainland%u2014by a narrow causeway that is covered with water during high tide. The Benedictine Abbey was founded in the 10th century, and has undergone many transformations since. Now it is a memorable complex of various buildings and styles%u2014including rounded Romanesque arches and lacy Gothic vaulting%u2014all culminating in a dramatic pointed spire. A major pilgrimage site for centuries, it was turned into a prison during the French Revolution, and the Benedictines did not return until 1966.”
