Discovered in 1886 during construction work on the railway, the Devèze cave is nicknamed the "Palais de la fileuse de verre" for the remarkable finesse of its concretions: "Aragonite flowers", a large petrified waterfall, impressive and imposing stalagmite, then an "altar" and its bright white candle, stalactites real mineral sculptures (rings, sickle, butterfly ...) and astonishing draperies tinted white to dark ochre.
