Bex Salt Mines history

Between 200 to 600 million years ago, the Rhône Valley was a shallow sea, and it is from this sea that the great salt deposits of Bex within the Canton of Vaud originate. The salt mines were not discovered until 1554 in Switzerland, and production of salt quickly followed with a salt works built in Roche. Initially run by foreign nobles, in 1685 the mines came under control of the Bernese state.

As the mines demanded large amounts of wood, in 1695 a forest was planted in the Joux Verte gorge. The trees and their natural evaporation was replaced with boiling in the 17th century to speed salt production. As demand grew, tunnels were dug to find new sources, which included deposits at Le Bévieux and Les Devens.

Today, you can descend the well-lit staircase within the immense cavernous dark of the Bex Salt Mines. This working salt mine produces 30,000 tons of salt per year, and is comprised of a labyrinth of tunnels over 50 km long. When visiting the museum and mines, visitors can learn about the various techniques of salt mining that date back to 1684.
