Mont-Saint-Michel, France

Mont-Saint-Michel,

Mont Saint-Michel is a rocky tidal island 247 acres (100 ha) in size, and is a commune in Normandy, France. It is located approximately one kilometre (just over half a mile) off the country's northwestern coast, at the mouth of the Couesnon River near Avranches. The island's highest point is 92 metres (301 feet) above sea level. The population of the island is 44, as of 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 and farmers housing.

One of France's most recognisable landmarks, Mont Saint-Michel and its bay are part of the UNESCO list of World Heritage Sites and more than 3 million people visit it each year.

Geography 

Formation[edit]

In prehistoric times the bay was land. As sea levels rose, erosion shaped the coastal landscape over thousands of years. Several blocks of granite or granulite emerged in the bay, having resisted the wear and tear of the ocean better than the surrounding rocks. These included Lillemer, the Mont-Dol, Tombelaine (the island just to the north), and Mont Tombe, later called Mont Saint-Michel. The Mont has a circumference of about 960 meters and 92 meters at its highest

Tides[edit]

The tides in the area change quickly, and have been described by Victor Hugo as swiftly as a galloping horse".

The tides can vary greatly, at roughly 14 metres (46 ft) between high and low water marks. Popularly nicknamed "St. Michael in peril of the sea" by medieval pilgrims making their way across the flats, the mount can still pose dangers for visitors who avoid the causeway and attempt the hazardous walk across the sands from the neighbouring coast.

Polderisation and occasional flooding created salt marsh meadows that were found to be ideally suited to grazing sheep. The well-flavoured meat that results from the diet of the sheep in the pré salé (salt meadow) makes agneau de pré-salé (salt meadow lamb), a local specialty that may be found on the menus of restaurants that depend on income from the many visitors to the mount.

Tidal island[edit]

Low tide in 2005

Mont Saint-Michel was previously connected to the mainland via a tidal causeway, i.e., a trackway covered at high tide and revealed at low tide. This connection has been altered over the centuries. The coastal flats have been polderised to create pastureland, thus the distance between the shore and the south coast of Mont Saint-Michel has decreased, and the Couesnon River has been canalised, reducing the dispersion of the flow of water, and thereby encouraging a silting-up of the bay. In 1879, the tidal causeway was converted into a raised or dry causeway. This prevented the tide from scouring the silt around the mount.

On 16 June 2006, the French prime minister and regional authorities announced a €164 million project (Projet Mont-Saint-Michel) to build a hydraulic dam using the waters of the river Couesnon and of tides to help remove the accumulated silt deposited by the rising tides, and to make Mont Saint-Michel an island again. It was projected to be completed by 2015.

The construction of the dam began in 2009 and is now complete. The project also included the removal of the causeway and its visitor car-park. It will be replaced by a light bridge, allowing the waters to flow freely around the island, which will improve the efficiency of the now operational dam, and a replacement car-park on the mainland. Visitors will use small shuttles to cross the future bridge which will still be open to pedestrians and unmotorised vehicles.
