Rising up from the Atlantic like a magical, fairy-tale palace, Mont Saint-Michel in France is one of the world's most iconic historical landmarks. MONT SAINT-MICHEL: RESISTANCE THROUGH THE AGES tells its 13 centuries-long story, exploring areas rarely seen by visitors and combining full-access filming with expert interviews and stunning illustrative graphics. Located at the border of Brittany and Normandy, the island commune of Mont Saint-Michel is a UNESCO World Heritage Site. Having been a place of worship and a prison, Mont Saint-Michel was left largely abandoned until recent decades when it was rediscovered by pilgrims and tourists keen to see this impressive complex for themselves. Its legends, myths and enduring mysteries are all investigated in this definitive film which will not only appeal to lovers of history but to anyone fascinated by the enduring ingenuity and vision of man. Erected on a large granite rock in the sea, the impressive Romanesque Benedictine Abbey is only reachable by foot when the tide is out, yet it receives more than 2.5 million visitors a year, making it the third busiest monument in all of France. This documentary explores the immense engineering challenges that came with building this so-called marvel of the western world which includes the abbey, the Merveille (the monks' living quarters), an amazing spire dedicated to the Archangel Michael, and a village. Its island location - connected with a land bridge but twice a day - has been the biggest hurdle of all in protecting and preserving the structure in the face of natural disasters. And, English attacks and demolition have provided ongoing challenges throughout the centuries.
