Abbey of Saint Gall
Between 929 and 933, the Muslims of Fraxinetum extended their control to the more easterly Alpine passes and raided the Upper Rhône Valley. In 939, crossing the Alps again, they attacked the Abbey of Saint Gall and razed the Abbey of Saint-Maurice d'Agaune. Like the contemporary Vikings, the Muslim raiders target monasteries because of their wealth and lack of defences.
