La Mine bleue

La Mine bleue is a former underground slate quarry with large extraction chambers where workers once removed stone. The site features a network of galleries that reveal the structure of the mining operation and the practical methods used to cut and transport the stone.

The operation began in 1916 and quickly became one of the main sources of slate production in the region. Production peaked during the 1930s when the mine was in full operation and employed many workers from the surrounding communities.

The galleries display tools and personal objects that belonged to miners from the early 20th century. Walking through, you understand how the mining work shaped life in this region and what daily labor meant for the families who depended on this industry.

Visitors should prepare for cool temperatures since the underground chambers remain cold year-round. Sturdy footwear and reasonable physical fitness help ensure a safe and comfortable experience while moving through the galleries.

Access to the deepest galleries is provided by a modern elevator that transports visitors directly into the heart of the mine. This blend of preserved 20th century working spaces with contemporary visitor infrastructure creates an interesting contrast worth noticing.
