The Mont-Saint-Michel is one of Europe’s most unforgettable sights. Set in the mesmerising bay where Normandy and Brittany merge, the island draws the eye from great distances. The staggering location has long inspired awe and the imagination. The story of how the mount turned into a great place of Christian pilgrimage is colourful. Aubert, bishop of the nearby hilltop town of Avranches early in the 8th century, claimed that the Archangel Michael himself pressured him into having a church built atop the island just out to sea. From 966 onwards, the dukes of Normandy, followed by French kings, supported the development of a major Benedictine abbey on the Mont-Saint-Michel. Magnificent monastic buildings were added through medieval times, one vertiginous section being nicknamed The Marvel. The abbey became a renowned centre of learning, attracting some of the greatest minds and manuscript illuminators in Europe.
