Mont Saint-Michel (English: Mount Saint Michael) is a rocky tidal island in Normandy, France. It is located approximately one kilometer off the country’s north coast, at the mouth of the Couesnon River near Avranches.
Mont Saint-Michel was used in the sixth and seventh centuries as an Armorican stronghold of Romano-Breton culture and power, until it was ransacked by the Franks, thus ending the trans-channel culture that had stood since the departure of the Romans in AD 460.
Before the construction of the first monastic establishment in the 8th century, the island was called Mont Tombe. According to legend, the archangel Michael appeared to St. Aubert, bishop of Avranches, in 708 and instructed him to build a church on the rocky islet. Aubert repeatedly ignored the angel’s instruction, until Michael burned a hole in the bishop’s skull with his finger.
The mount gained strategic significance in 933 when William “Long Sword”, Duke of Normandy, annexed the Cotentin Peninsula, definitively placing the mount in Normandy. It is depicted in the Bayeux Tapestry, which commemorates the 1066 Norman conquest of England. Ducal patronage financed the spectacular Norman architecture of the abbey in subsequent centuries.
