Several unusual attractions hide on the rooftop of this sprawling train station, reached by the metal staircase next to platform 1 or lifts/elevators on rue du Commandant Rene Mouchotte. The Jardin de l’Atlantique , whose 3.5 hectares carpets the station's roof, offers greenery and tranquillity in the heart of the urban tumult. Its futuristic Observatoire Météorologique ‘sculpture’ measures precipitation, temperature and wind speed. Next to the garden is the Resistance museum, the Musée Jean Moulin .
Devoted to the WWII German occupation of Paris, the small museum focuses on the Resistance and its leader, Jean Moulin (1899–1943). The attached Mémorial du Maréchal Leclerc de Hauteclocque et de la Libération de Paris shows a panoramic film on the eponymous general (1902–47), who led the Free French units during the war and helped to liberate the city in 1944.
