Deep beneath the Chemin des Dames plateau lies the Caverne du Dragon, a former limestone quarry that was transformed into a strategic underground fortress during the First World War. From 1915, German troops took over the cave and built dormitories, a chapel, an aid station and even an electricity network. Later, the cave was partially retaken by the French, and both armies temporarily lived side by side, separated by walls in the darkness. The name “Caverne du Dragon” (Drachenhöhle) refers to the mythical dragon from Germanic legends, inspired by the smoke that rose from the loopholes as if from the mouth of a monster. Today, the cave is a museum and memorial site, where visitors can explore the underground passages and experience the traces of soldiers’ lives in the depths.

You can explore the two largest caves, with a length of 21 m and 36 m respectively, or admire the impressive stack of blocks which forms a large shelter on the side of the valley. The site is also rich in history and legend, as it is said to be where the Irish monk Goban settled in the 7th century and performed many miraculous healings.

The caves at the bottom of Guesot in Fontenoy are part of a natural site which includes the slopes of Port-Fontenoy and the Ru de Vaux valley. The caves are home to rare bats that hibernate there in winter, and also contain prehistoric carvings on the walls. The caves are not open to the public, so you will need to obtain special permission from the Conservatory of Natural Sites of Picardy before you can visit them. On the other hand, you can admire them from the outside while running.
