Precious stone mines
This former mine is the only one of its kind in Europe open to the public. Its 400m of tunnels and galleries offer the opportunity to see and understand the formation of semi-precious stones still trapped in the volcanic rock. There is also a section of the mine where visitors can have a go at looking for precious stones themselves by digging into the rock.
