Since 2015, three new exhibition halls are now open to the public. The museography has been entirely rethought and modernised to encourage visitors to wander through an interactive and educational museum area dedicated to younger audiences. The museum also spurs on visitors to discover the region’s geology, the evolution of quarrying over a period of more than 600 years, the daily life of slate workers, the quarry landscape and mining objects.
