The hidden history of modernism in the mountains. In southern France, high above the villas and pleasure palaces of the Côte d’Azur, lies the Alpine Extension of the Maginot Line. These little-known fortifications were built before the Second World War to protect France from Mussolini. But nobody has successfully invaded over the Alps since Napoleon, and things didn’t quite turn out as the French expected… Now the bunkers are marooned, forlorn and crumbling, in some of the most beautiful and remote parts of France, disappearing into the landscapes they once commanded, stray facts from a future passed, still waiting for an onslaught that never came. Writer Max Leonard and photographer Camille McMillan uncover and document these hidden sites.
