The museum with the longest name in Paris opened in 2019 in time for the 75th anniversary of the Liberation of Paris, and is a must for anyone interested in World War II history. Housed in brand-new buildings at Denfert-Rochereau (including revamped 18th-century pavilions built by the neoclassicist architect Nicolas Le Doux), the museum retraces the history of the Résistance and the figures who helped liberate France—notably Général Leclerc de Hautclocque (who famously joined De Gaulle’s government-in-exile in Britain and furthered the Allied cause in Africa) and Jean Moulin, the head of the Résistance. The museum leads you through wartime events, with displays of around 300 items, including official documents and rare film archives. Part of the visit takes you through the underground bunker where Colonel Rol-Tanguy planned the Liberation of Paris.
