 In France, the famous abbeys of Aux Dames and Les Hommes at Caen and Mont Saint-Michel date from this period, as well as the abbeys of the pilgrimage route to Santiago de Compostela.Many cathedrals owe their foundation to this date, with others beginning as abbey churches, and later becoming cathedrals.In England, of the cathedrals of ancient foundation, all were begun in this period with the exception of Salisbury, where the monks relocated from the Norman church at Old Sarum, and several, such as Canterbury, which were rebuilt on the site of Saxon churches.
