Haut-Martelange Slate Museum

The Haut-Martelange Slate Museum is a mining museum in a former extraction site that shows how slate was quarried and processed. Underground passages lead down to depths of around 42 meters, where you can see the original working conditions.

Slate extraction began here around 1790 and continued until 1986, with workers manually quarrying and shaping stone. The techniques were passed down over many generations and shape how this craft tradition is understood today.

The place preserves the memory of generations who spent their lives working underground in the slate industry. Visitors encounter people demonstrating traditional splitting techniques and sharing stories from their working years.

Visitors receive helmets for exploring the underground areas and should wear sturdy footwear. Access is only possible with a guide, and some sections may be restricted depending on weather conditions.

The museum grounds include a small rail car that visitors can ride through parts of the facility. This ride gives you a direct sense of how raw materials were transported in the past.
