Mont Saint Michel or Le Mont Saint-Michel is an island community in Normandy, France. Named after the arch-angel St. Michael, it is known as the Wonder of the Western World. The monument, a small rocky island, was built on 100 hectares (247 acres), about a kilometre to northwestern coast of the country at the mouth of the Couesnon River near Avranches.
Mont Saint Michel is characterized by the highest tides, up to 14 meters high, steep rocks, and quicksand. The water surrounding Mont St Michel can move 18 kilometers away from the island and 20 kilometers deep into the coast. Mont Saint-Michel was built with granite from the nearby Islands of Chausey. Construction of the original abbey/ church structure took more than 500 years, from 1017 to 1521. The church was completed in 1144 and the other buildings were added later in 13th century. These buildings were used as a place of residence by the monks and piligrims who visited the abbey. Its monastery flourished as one of the great places of learning in the 12th century.
