A millennium-old monument of a worldwide renown, Mont-Saint-Michel captivates us with the virtuosity of its architecture. Since its founding more than thirteen centuries ago, it has remained a gripping enigma for all those who explore its secrets.
A major pilgrimage site, an impregnable monastery that withstood the English during the Hundred Years’ War, a state prison… A true architectural marvel, Mont-Saint-Michel is still far from having revealed all its secrets. How did the builders manage to erect such a complex structure – rising more than 150 meters high – on a 960-meter-wide rock, defying the laws of balance? And how has Mont-Saint-Michel managed to resist the onslaught of history and the elements for over a thousand years?
Through 3D reconstructions and exclusive access, we explore the hidden side of Mont-Saint-Michel – a buried chapel, crypts, tunnels, invisible galleries – alongside experts who are attempting to unravel its final mysteries.
