Le Mont-Saint-Michel is a tidal island and mainland commune in Normandy, France.
The island lies approximately one kilometre (0.6 miles) off the country's north-western coast, at the mouth of the Couesnon River near Avranchesand is 7 hectares (17 acres) in area.
This island, with its fast and fickle tides, was a notorious prison during the French Revolution. Today, visitors arrive by choice, seeking to explore the 11th-century abbey, dine in fine restaurants and take in the impressive evening illuminations. Only a narrow causeway built in 1880 links the island to the mainland, although a bridge is due to be completed in 2012.
