Mont Saint-Michel by @thomas_ov4 Mont Saint-Michel is a stunning island commune located in Normandy, France, famous for its dramatic setting and medieval architecture. Rising out of tidal waters in the bay where Normandy and Brittany meet, it is crowned by a magnificent Gothic-style abbey dedicated to the Archangel Michael. The site’s religious history dates back to 708 AD, when Bishop Aubert of Avranches claimed that the Archangel Michael instructed him to build a sanctuary on the rocky island.
