The Archives of the Jura offer you to discover original documents presented in windows in the reading room. These documents come from two private collections recently entered and filed in the Archives: the Grandclément Filmmaking Collection in Viry and the Raoul Prost-Rosset Collection, a metal meter manufacturer in Longchaumois. Explanatory panels trace the history of these two companies, which testify to the national and international recognition of Jura know-how.
