Mont Saint-Michel is a historic island town in northwestern France, located in the bay between Normandy and Brittany. This unique architectural complex includes a medieval abbey and monastery built on a high granite island, which becomes a peninsula at low tide and is surrounded by the waters of the bay at high tide.

Mont Saint-Michel is famous for its impressive architecture, including an abbey church with a high Gothic gallery and narrow streets that lead to the top of the town. In 1979, it was included in the UNESCO World Heritage List as a historical monument that combines architectural and natural heritage.
