Mont-Saint-MichelWith two hyphens and the French article "Le" ahead, because it is the name of a commune, not a hill. (; Norman: Mont Saint Miché; ) is a tidal island and mainland commune in Normandy, France.

The island lies approximately one kilometre (half a nautical mile) off France's north-western coast, at the mouth of the Couesnon River near Avranches and is in area. The mainland part of the commune is in area so that the total surface of the commune is . , the island has a population of 23.

The commune's position—on an island just a few hundred metres from land—made it accessible at low tide to the many pilgrims to its abbey, and defensible as the incoming tide stranded, drove off, or drowned threats on foot. The island remained unconquered during the Hundred Years' War. A small garrison fended off a full attack by the English in 1433. Louis XI recognised the benefits of its natural defence and turned it into a prison. The abbey was used regularly as a prison during the Ancien Régime.

Mont-Saint-Michel and its surrounding bay were inscribed on the UNESCO list of World Heritage Sites in 1979 for its unique aesthetic and importance as a Catholic site. It is visited by more than three million people each year, and is the most-visited tourist attraction in France outside of Paris. Over 60 buildings within the commune are protected as historical monuments.

Geography

Formation Now a rocky tidal island, the mount occupied dry land in prehistoric times. As sea levels rose, erosion reshaped the coastal landscape, and several outcrops of granite emerged in the bay, having resisted the wear and tear of the ocean better than the surrounding rocks. These included Lillemer, Mont Dol, Tombelaine (the island just to the north), and Mont Tombe, later called Mont-Saint-Michel.

Mont-Saint-Michel consists of leucogranite which solidified from an underground intrusion of molten magma about , during the Cambrian period, as one of the younger parts of the Mancellian granitic batholith. Early studies of Mont-Saint-Michel by French geologists sometimes describe the leucogranite of the Mont as "granulite", but this granitic meaning of granulite is now obsolete.

The mount has a circumference of about and its highest point is above sea level.Chantal Bonnot-Courtois, La Baie du Mont-Saint-Michel et l'estuaire de la Rance: environnements sédimentaires, aménagements et évolution récente. Editor Technip. 2002. pp. 15–20.

Tides The tides vary greatly, at roughly between highest and lowest 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 bridge and attempt the hazardous walk across the sands from the neighbouring coast.

Polderisation and occasional flooding have created salt marsh meadows that were found to be ideally suited to grazing sheep. (), 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

The connection between Mont-Saint-Michel and the mainland has changed over the centuries. Previously connected by tidal causeway uncovered only at low tide, this was converted into a raised causeway in 1879, preventing the tide from scouring the silt around the mount. The coastal flats have been polderised to create pastureland, decreasing the distance between the shore and the island, and the Couesnon river has been canalised, reducing the dispersion of the flow of water. These factors have all encouraged silting-up of the bay.

In June 2006, French prime minister Dominique de Villepin and regional authorities announced a project () to build a hydraulic dam using the waters of the Couesnon and the tides to help remove the accumulated silt, and to make Mont-Saint-Michel an island again. The construction of the dam began in 2009. The project included the removal of the causeway and its visitor car park. Since April 2012, the new car park on the mainland has been located from the island. Visitors can walk or use shuttles to cross the bridge.

In July 2014, the new bridge, by architect Dietmar Feichtinger, was opened to the public. The light bridge allows waters to flow freely around the island and improves the efficiency of the now-operational dam. The bridge, which cost , was opened by President François Hollande.

On rare occasions, tidal circumstances produce an extremely high "supertide". The new bridge was completely submerged on 21 March 2015 by the highest sea level, a once-in-18-years occurrence, as crowds gathered to snap photos.

History 8th century onward Before the construction of the first monastic establishment in the 8th century, the island was called Mont Tombe (). According to a legend, the archangel Michael appeared in 708 to Aubert of Avranches, the bishop of Avranches, and instructed him to build a church on the rocky islet.

Unable to defend his kingdom against the assaults of the Vikings, the king of the Franks agreed to grant the Cotentin Peninsula and the Avranchin, including Mont-Saint-Michel traditionally linked to the city of Avranches, to the Bretons in the Treaty of Compiègne. This marked the beginning of a brief period of Breton possession of the Mont. In fact, these lands and Mont-Saint-Michel were never really included in the duchy of Brittany. Around 989–990 these traditional bishoprics, dependent of the archbishopric of Rouen and that had been left vacant during the time of the Viking raids, regained their bishops.Allen, Richard, The Norman Episcopate, 989-1110, University of Glasgow, 2009, fig. 3, p. 14

The mount gained strategic significance again in 933 when William I Longsword annexed the Cotentin Peninsula from the weakened Duchy of Brittany. This made the mount definitively part of Normandy, and is depicted in the Bayeux Tapestry, which commemorates the Norman Conquest. Harold Godwinson is pictured on the tapestry rescuing two Norman knights from the quicksand in the tidal flats during the Breton–Norman war. Norman ducal patronage financed the spectacular Norman architecture of the abbey in subsequent centuries.

In 1067, the monastery of Mont-Saint-Michel gave its support to William the Conqueror in his claim to the English throne. This he rewarded with properties and grounds on the English side of the Channel, including a small island off the southwestern coast of Cornwall which was modelled after Mont-Saint-Michel and became a Norman priory named St Michael's Mount of Penzance.

14th century Under the rule of the 29th abbot, Pierre le Roy, from 1386 to 1410, new fortifications were built: at the northeast corner of the Merveille, an octagonal crowning element was added to the Corbins tower; at its base, a long curtain wall-terrace overlooking the woods. In 1393, two turrets were added to flank the 1257 gate. Large steps were built in front of the barbican, and the abbot had a fortified residence built, as well as the square-based Pénine tower, designed to guard the Grand Degré.

During the Hundred Years' War, English forces unsuccessfully besieged Mont-Saint-Michel (which was under French control) twice. The first siege started in 1423, and was lifted the next year. In 1433, an English force equipped with wrought-iron bombards and under the command of Thomas Scales, 7th Baron Scales again besieged the island. It was likewise lifted the next year. Scales's men abandoned two bombards they had used during the siege on 17 June 1434; they were recovered by the French and are currently on display.

When Louis XI of France founded the Order of Saint Michael in 1469, he intended that the abbey church of Mont-Saint-Michel become the chapel for the order, but because of its great distance from Paris, his intention could never be realized. Recent times The wealth and influence of the abbey extended to many daughter foundations, including St Michael's Mount in Cornwall. Its popularity and prestige as a centre of pilgrimage waned with the Reformation, and by the time of the French Revolution there were scarcely any monks in residence. The abbey was closed and converted into a prison, initially to hold clerical opponents of the republican regime. High-profile political prisoners followed. By 1836, influential figures—including Victor Hugo—had launched a campaign to restore what was seen as a national architectural treasure. The prison was closed in 1863.

In 1872, French architect of historic monuments Édouard Corroyer was responsible for assessing the condition of Mont-Saint-Michel. It took him about two years to convince his minister to classify it as a historic monument, and it was officially declared as such in 1874. From then on Corroyer, a member of the Academy of Fine Arts, devoted fifteen years of his life to the restoration of "". Under his direction, gigantic works were undertaken, starting with the most urgent. He wrote four works on the building.

During the occupation of France in World War II, German soldiers occupied Mont-Saint-Michel, where they used St. Aubert church as a lookout post. The island was a major attraction for German tourists and soldiers, with around 325,000 German tourists from July 18, 1940, to the end of the occupation of France.

After the Allies' initial D-Day invasion of Normandy that began on June 6, 1944, many exhausted German soldiers retreated to strongholds like Mont-Saint-Michel. On August 1, 1944, a single American soldier – Private Freeman Brougher, from Pennsylvania, of the 72nd Publicity Service Battalion (a small Anglo-American psychological warfare unit) – reached and liberated Mont-Saint-Michel accompanied by two British reporters, Gault MacGowan of the New York Sun and Paul Holt with the London Daily Express. Jubilant crowds of locals greeted Brougher, Holt and MacGowan, and Brougher signed the Golden Book, the island's record of visiting nobility, at the mayor's invitation. The abbey was also used as a prison for the first time since the French Revolution when male collaborators with the Germans were jailed there.

Mont-Saint-Michel and its bay were added to the UNESCO list of World Heritage Sites in 1979, listed with criteria such as cultural, historical, and architectural significance, as well as human-created and natural beauty.

In June 2023, President Emmanuel Macron visited Mont-Saint-Michel to mark the abbey's millennium. He stated that the changes since the hydraulic dam and the new bridge opened have lessened the silting, making it an island again.

Abbey design

In the 11th century, William of Volpiano, the Italian architect who had built Fécamp Abbey in Normandy, was chosen by Richard II, Duke of Normandy, to be the building contractor. He designed the Romanesque church of the abbey, daringly placing the transept crossing at the top of the mount. Many underground crypts and chapels had to be built to compensate for this weight. These formed the basis for the supportive upward structure that can be seen today. Today Mont-Saint-Michel is seen as a building of Romanesque architecture.

Robert de Thorigny, a great supporter of Henry II of England, who was also Duke of Normandy, reinforced the structure of the buildings and built the main façade of the church in the 12th century. In 1204, Guy of Thouars, regent for the Duchess of Brittany, as vassal of the King of France, undertook a siege of the Mount. After setting fire to the village and massacring the population, he beat a retreat under the powerful walls of the abbey. The fire which he lit extended to the buildings, and the roofs fell prey to the flames. Horrified by the cruelty of his Breton ally, Philip Augustus offered Abbot Jordan a grant for the reconstruction of the abbey in the new Gothic architectural style.

Charles VI is credited with adding major fortifications to the abbey-mount, building towers, successive courtyards, and strengthening the ramparts.
