This museum pays tribute to two men, Philippe de Hautecloque, future General Leclerc, and Jean Moulin, both of whom decided to join the fight against German occupation to defend freedom and liberate their country in June 1940. Objects, photos, videos and digital and interactive displays chart this historic period. The highlight is the visit of the underground HQ, established in August 1944 by Henri-Rol Tanguy, head of the Free French Forces.
