The Musée de la Chartreuse - Fondation Bugatti l'heure goes archaeological for the weekend.
During these workshops, prehistorian Michel Mauvilly will demonstrate how Neolithic humans drilled, sawed and cut the stones they used to make tools.
There's also a workshop on "Neolithic stonework: drilling, sawing and cutting", and a guided tour of the "100,000 years of history in the Bruche valley and Vosges foothills" exhibition.
