In the 8th century, Aubert, Bishop of Avranches (a nearby hilltop town), had a vision of the Archangel Michael. To honour the archangel, he erected a small chapel at Mont Saint Michel island. By 966, Benedictine monks settled there. The Benedictine Mont Saint Michel Abbey flourished, becoming a centre of religious and cultural activity. A large number of pilgrims- including Kings of France and England, visited it over centuries. As a hub of medieval culture, Saint Mont Michel produced and stored manuscripts. It flourished to become an important pilgrimage site for Christians, from the 8th to the 18th century.
