This activity is specially designed for children. Young explorers will discover the fascinating world of slate—from its natural formation to extraction and transformation into a finished product. The story of this iconic stone is revealed in a fun and accessible way. Following in the footsteps of old slate workers, children go 42 meters underground for a family-friendly guided tour and explore the Johanna underground quarry. The adventure continues in the workshop spaces: time for creativity! Each child carves their own slate medallion and takes home a personal souvenir from this underground experience.
