Mont Saint-Michel is a small UNESCO World Heritage site on an island just off the coast near Avranches in the region of Lower Normandy in northern France. The island is best known as the site of the spectacular and well-preserved Norman Benedictine Abbey of St Michel at the peak of the rocky island, surrounded by the winding streets and convoluted architecture of the medieval town.
Mont Saint-Michel was inscribed as a World Heritage Site in 1979. Mont-Saint-Michel was used in the 6th and 7th 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 "monte 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.
