Mont Saint-Michel (pronounced: [mɔ̃ sɛ̃ mi.ʃɛl]; English: Saint Michael's Mount) is a rocky tidal island and a commune in Normandy, France. It is located approximately one kilometre (just over half a mile) off the country's north-western coast, at the mouth of the Couesnon River near Avranches. The population of the island is 41, as of 2006. The island has been a strategic point holding fortifications since ancient times, and since the 8th century AD it became the seat of the Saint-Michel monastery, from which it draws the name. The Mont-Saint-Michel and its bay are part of the UNESCO list of World Heritage Sites. More than 3,000,000 people visit it each year.
