Mont Saint-Michel is a rocky tidal island in Normandy, France. It is located approximately one kilometre off the country’s north coast, at the mouth of the Couesnon River near Avranches. The population of the island is 41.
In prehistoric times the bay was land. As sea levels rose, erosion shaped the coastal landscape over millions of years. Several blocks of granite 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.
Mont-Saint-Michel was used in the sixth and seventh centuries as an Armorican stronghold of Romano-Breton culture and power, until it was ransacked by the Franks, thus ending the trans-channel culture that had stood since the departure of the Romans in AD 460.
Before the construction of the first monastic establishment in the 8th century, the island was called “monte tombe”. According to legend, St. Michael the Archangel appeared to St. Aubert, bishop of Avranches, in 708 and instructed him to build a church on the rocky islet.
Aubert repeatedly ignored the angel’s instruction, until St. Michael burned a hole in the bishop’s skull with his finger.
The mount gained strategic significance in 933 when William “Long Sword”, William I, Duke of Normandy, annexed the Cotentin Peninsula, definitively placing the mount in Normandy.
In 966 a community of Benedictines settled on the rock at the request of the Duke of Normandy and the pre-Romanesque church was built before the year one thousand.
William de Volpiano, the Italian architect who had built the Abbey of Fécamp in Normandy, was chosen as building contractor by Richard II of Normandy in the 11th century. 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 Gothic-style church.![]()
In 1067, the monastery of Mont-Saint-Michel gave its support to duke William of Normandy in his claim to the throne of England. It was rewarded with properties and grounds on the English side of the Channel, including a small island located to the west of Cornwall, which was modelled after the Mount, and became a Norman priory named St Michael’s Mount of Penzance.
In the 12th century, the Romanesque monastery buildings were extended to the west and south. 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 1204 the Breton Guy de Thouars, allied to the King of France, undertook the siege of the Mount. After having set fire to the village and having massacred the population, he was obliged to beat a retreat under the powerful walls of the abbey. ![]()
Unfortunately, the fire which he himself lit extended to the buildings, and the roofs fell prey to the flames. Horrified by the cruelty and the exactions of his Breton ally, the king of France Philip Augustus offered Abbot Jourdain a grant for the construction of a new Gothic-style architectural set which included the addition of the refectory and cloister.
In the 14th century, the Hundred Years War made it necessary to protect the abbey behind a set of military constructions, enabling it to hold out against a siege lasting 30 years. Charles VI is credited with adding major fortifications to the abbey-mount, building towers, successive courtyards and strengthening the ramparts.
In the 15th century, the Romanesque chancel of the abbey church, broken down in 1421 was replaced by the Gothic Flamboyant chancel.![]()
With Rome and Compostela (Spain) this great spiritual and intellectual centre, was one of the most important places of pilgrimage for the Medieval occident. For nearly one thousand years men, women and children went there by roads called « paths to paradise » hoping for the assurance of eternity, given by the Archangel of judgement « Peseur des ames ».
The wealth and influence of the abbey extended to many daughter foundations, including St Michael’s Mount in Cornwall. However, 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 régime. High-profile political prisoners followed, but by 1836, influential figures – including Victor Hugo – had launched a campaign to restore what was seen as a national architectural treasure.
The prison was finally closed in 1863, and the mount was declared a historic monument in 1874.
With the celebration of the monastic’s 1000th anniversary,in the year 1966 a religious community moved back to what used to be the abbatial dwellings, perpetuating prayer and returning to the original vocation of this place. Friars and sisters from “Les Fraternités Monastiques de Jerusalem” have been ensuring a spiritual presence since the year 2001.![]()
At the same time as the abbey was developing a village grew up from the Middle Ages. It flourished on the south-east side of the rock surrounded by walls dated for the most part from the Hundred Years war.
The Mont-Saint-Michel and its bay were added to the UNESCO list of World Heritage Sites in 1979.
Mont Saint-Michel was previously connected to the mainland via a thin natural land bridge, which before modernization was covered at high tide and revealed at low tide. Over the centuries, the coastal flats have been polderized to create pasture.
Thus the distance between the shore and the south coast of Mont-Saint-Michel has decreased. The Couesnon River has been canalized, reducing the flow of water and thereby encouraging a silting-up of the bay. In 1879, the land bridge was fortified into a true causeway. This prevented the tide from scouring the silt around the mount.![]()
In 2006, the French prime minister and regional authorities announced a €164 million project 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.
The construction of the dam began in 2009 and is now complete. The project also included the destruction of the causeway that had been built on top of the small land bridge and enlarged to join the island to the continent. It will be replaced by an elevated light bridge, under which the waters will flow more freely.
The tides in the area change quickly, and have been described by Victor Hugo as “à la vitesse d’un cheval au galop” or “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.

I am so glad to read that Mont St Michael is once again a place of beauty and that the monastery has been rescued from being just a historical monument to take it’s rightful place once again to glorify God.
Thank you Jonie for all you do to shine in our lives through Jesus Christ xxx
