Mont Saint Michel - France

 Saint Michael's Mount is an island commune in Normandy, France. It is located about one kilometre (0.6 miles) off the country's northwestern coast, at the mouth of the Couesnon River near Avranches and is 100 hectares (247 acres) in size. The island has held strategic fortifications since ancient times and since the 8th century AD has been the seat of the monastery from which it draws its name. The commune's position — on an island just 600 metres from land — made it accessible at low tide to the many pilgrims to its abbey, but defensible as an incoming tide stranded, drove off, or drowned would-be assailants. One of France's most recognizable landmarks, visited by more than 3 million people each year, Mont Saint-Michel and its bay are on the UNESCO list of World Heritage Sites.
