Origin from 708
A rocky tidal island off the Normandy coast crowned by an abbey dedicated to the archangel Michael, and one of the most visited places in France. The tide here has the greatest range in continental Europe and can cross the sand faster than a person walks, which is the fact the whole site turns on: the island was cut off twice a day for most of its history, and the causeway that had ended that was deliberately replaced in 2014 by a bridge on piles so that the sea could flow around it again. A monastic community keeps the offices in the abbey church, and the village below has a resident population of a few dozen against several million annual visitors.

An Abbey the Sea Cuts Off Twice a Day
Mont Saint-Michel is a rocky tidal island off Normandy crowned by a medieval abbey of the archangel Michael, a site whose whole character is set by the extreme tide that surrounds it.
The tide and the mount
The bay has the greatest tidal range in continental Europe; the sea can retreat kilometres and return, it is said, as fast as a horse can gallop, and for most of its history the island was cut off from the mainland twice a day. According to tradition the sanctuary was founded in 708 after the archangel Michael appeared to Aubert, bishop of nearby Avranches, instructing him to build a church on the rock. A Benedictine abbey was established there in the tenth century.
The abbey on the summit
Over the following centuries monks and masons raised an increasingly ambitious complex up the steep sides of the granite cone, culminating in the Romanesque and Gothic abbey church at the summit and the remarkable three-storey monastic buildings known as the Merveille, the "Marvel", clinging to the north face. The engineering of building a great church on a pinnacle of rock is itself part of the site's meaning; the archangel who weighs souls and leads the heavenly host is fittingly enshrined on a height between earth and sky.
Fortress, prison, pilgrimage
The mount held out as a fortress during the Hundred Years War, was later used as a prison, and was restored as a monument and returned to religious use. A monastic community again keeps the daily offices there. In 2014 the causeway that had joined it to the mainland was deliberately replaced by a bridge on piles so that the sea could once more flow all the way around the island, restoring its island character. It is a World Heritage site and among the most visited places in France, with a resident population of a few dozen against several million annual visitors.
Prison, Then Novelist, Then Engineers
Mont Saint-Michel spent seventy years as a prison before it spent any time as a tourist destination, and a novelist is largely credited with ending that.
From abbey to jail
After the French Revolution, the abbey buildings were converted into a prison, holding political and later criminal prisoners from 1793 until 1863. Cramped cells were fitted into halls built for monastic life, and the wear from that use is still visible in parts of the complex today, layered awkwardly under the medieval architecture around it.
Hugo's campaign
The writer Victor Hugo and other cultural figures campaigned publicly against the prison's continued use, arguing that it degraded a major national monument, and the prison was finally closed in 1863; restoration and a return of a small monastic community followed over subsequent decades.
Losing, then regaining, the tide
A causeway built in 1879 let vehicles reach the island but also caused silt to build up around it, and by the early twenty-first century the bay was at risk of turning the mount into a permanently landlocked hill. A large hydraulic engineering project, including a new bridge completed in 2014 that lets water flow freely beneath it and a dam on the nearby River Couesnon to flush silt, was built specifically to restore the twice-daily tidal isolation that had defined the site for most of its history.
