These 19th-century forts had already lost their invincibility in the second half of the century and were more of a "belt of remnants" that no longer played a major strategic role. It was only when the Chemin des Dames became a deadlock as a front area that they became relevant again for a short time. Here you can feel this survived history well, the cellar-like bunkering on the mountain. Almost a small green overgrown labyrinth today....
