Mont Saint-Michel is an island commune in Normandy, France. It is located approximately one kilometre (0.6 miles) off the country's northwestern coast, at the mouth of the Couesnon River near Avranches.

100 hectares (247 acres) in size, the island has a population of 44 (2009).
The island has held strategic fortifications since ancient times, and since the eighth century AD has been the seat of the monastery from which it draws its name. The structural composition of the town exemplifies the feudal society that constructed it: On top, God, the abbey and monastery; below this, the great halls; then stores and housing; and at the bottom, outside the walls, fishermen's and farmers' housing.
