Mont-Saint-Michel

A Fortress Through the Ages

Mont-Saint-Michel's position made it a natural fortress. During the Hundred Years' War (1337–1453), it was the only place in Normandy that never fell to the English — despite repeated sieges and a blockade that lasted over two decades. A garrison of just 119 knights held the mount against thousands. The narrow Grand Rue, the fortified gates, and the steep terrain made assault virtually impossible. The English gave up and went home. The mount became a symbol of French resistance — a role reprised in World War II, when it was one of the first sites liberated after D-Day.

During the Revolution, the monks were expelled and the abbey was converted into a prison — the — where political prisoners were held in appalling conditions. Victor Hugo visited in 1836 and called it "a toad in a reliquary." His campaign for its preservation, alongside the restoration movement that saved Notre-Dame, eventually led to the prison's closure in 1863 and the abbey's classification as a in 1874.

The Tides

The bay of Mont-Saint-Michel has the highest tidal range in continental Europe — up to 14 metres between low and high water during spring tides. At low tide, the sea retreats as far as 15 kilometres from the mount, exposing vast expanses of sand and mudflats. At high tide, the water rushes in at extraordinary speed — famously described as advancing "at the speed of a galloping horse" (which is slightly exaggerated but not by much: the tide can cover ground at 6 km/h).

The tidal flats are genuinely dangerous. Quicksand-like patches of can trap walkers, and the incoming tide can cut off retreat routes in minutes. Crossing the bay on foot is possible but must be done with a licensed guide. Since 2014, a new bridge-causeway has replaced the old road and parking lot that once blocked tidal flow, allowing the sea to circulate freely around the island again — restoring the maritime character that had been lost to siltation over the previous century.
