According to tradition, Archangel Michael appeared in 708 to Aubert, Bishop of Avranches, who founded a first sanctuary on Mont Tombe. Benedictines settled there in 966 and raised the abbey and the Gothic Merveille over the centuries.
A stronghold never taken during the Hundred Years' War, a prison after the Revolution and a historic monument in 1874, the Mont and its bay have been a UNESCO World Heritage Site since 1979. The abbey's manuscripts are kept at the Scriptorial in Avranches.
