In 1692, the Manufacture royale des Grandes Glaces was established in the abandoned castle of Saint-Gobain, which gave the later glass company Saint-Gobain its name. The factory developed and in 1986 it still supplied the glass for the pyramid of the Louvre. In 1993, it was announced that the factory would close and on 31 December 1995 the last activity of this historic establishment disappeared.

The Grottes des Roches de l'Ermitage are natural and artificial caves dug by erosion in the limestone rock. 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.
