The abbey perches 80 metres above the tidal flats, its spire visible from Avranches fifteen kilometres inland. Construction began in 708 when Aubert, bishop of Avranches, claimed the archangel Michael appeared to him three times demanding a sanctuary on the granite outcrop.
Benedictine monks raised the first oratory within a decade; by 966 Richard I, Duke of Normandy, had installed a monastic community that would endure through nine centuries of war, revolution, and abandonment.
The architecture spans Carolingian crypt to Flamboyant Gothic choir—layers of stone recording shifts in liturgy, wealth, and defensive need. The Grand Degré staircase climbs through the outer ramparts; the Merveille, a three-storey Gothic masterpiece completed in 1228, houses the refectory, cloister, and knights' hall. Pilgrims crossed the bay on foot during low tide, a journey that claimed lives when fog or storm obscured the channels. The causeway built in 1879 halted the natural scouring action of the tides; silt accumulated, and by the twentieth century the mount risked becoming landlocked. A hydraulic dam and bridge completed in 2014 restored tidal flow, reconnecting the site to the rhythms that shaped its isolation.
