Mont-Saint-Michel is a medieval abbey approximately 4 hours drive from Paris located in Normandy. With its massive walls, measuring more than half a mile in circumference surround, it is one of Europe's great attractions. Connected to the shore by a causeway, it crowns a rocky islet at the border between Normandy and Brittany. The rock is 78m (256 ft.) high. It sits atop a large conical outcropping that rises above the surrounding sea and coastal flatlands. It used to become an island on a twice-daily basis when the high tide encircled land mass. Though, today it doesn’t happen very often. It is one of the most important places of pilgrimage in Europe. Pilgrims used to take a boat or more often, they waited for the region’s high and swift tides to recede sufficiently to walk across the exposed sands, to go to and from Mont-St-Michel. Thanks to miscalculated tidal cycles many drowned and some also were swallowed by the area’s perilous quicksand.
