Paris Métro Line 12 is one of sixteen metro lines in the city. It links Issy-les-Moulineaux in southern Paris to Porte de la Chapelle in the north. The line has several important stops, such as Madeleine, the 6th arrondissement of Paris, Porte de Versailles and two national railway stations, Gare Montparnasse and Gare Saint-Lazare.
The service runs every day of the week, starting at 5:30; the last departure is at 0:39, or on Fridays and Saturdays, one hour later. The line uses MF 67 series trains which make a complete journey in 37 minutes.
Some stations are decorated thematically: Assemblée Nationale has murals depicting politicians’ silhouettes, and the tiling in Concorde represents an extract from the Declaration of the Rights of Man and Citizen in 1789.
