The stations of Lines 4 and 12 are located to the north under the Boulevard du Montparnasse while those of Lines 6 and 13 are south under Boulevard de Vaugirard and l'Avenue du Maine respectively.
History
On 24 April 1906 the station opened as Montparnasse station in the Avenue du Maine at the southern end of the old Gare Montparnasse with the opening of the extension of Line 2 Sud from Passy to Place d'Italie. On 14 October 1907Line 2 Sud became part of Line 5. On 11 March 1910 the Montparnasse station was renamed Avenue du Maine and on 30 June 1933 it was again renamed, to Bienvenüe in honour of the principal engineer of the Paris Métro, Fulgence Bienvenüe. On 12 October 1942 the section of Line 5 between Étoile and Place d'Italie, including Bienvenüe, was transferred from Line 5 to Line 6 in order to separate the underground and elevated sections of the Métro. The Line 4 platforms opened as Montparnasse in the Boulevard du Montparnasse, near the main entrance of the old Gare Montparnasse on 9 January 1910 as part of the connecting section of the line under the Seine between Châtelet and Raspail. The Line 12 platforms were opened in the Boulevard du Montparnasse on 5 November 1910 as part of the first section of the Nord-Sud Company's Line C from Porte de Versailles to Notre-Dame-de-Lorette. This line was taken over by the Compagnie du chemin de fer métropolitain de Paris and was renamed Line 12 on 27 March 1931. In 1913 a connection was opened between the platforms of Lines 4 and Line 12 situated on the Boulevard du Montparnasse, both called Montparnasse. The Line 13 platforms opened in the Avenue du Maine as Bienvenüe on 21 January 1937 as part of the original Line 14 between there and Porte de Vanves, and were connected to the Line 5 platforms. This line became part of Line 13 on 9 November 1976.
Connecting the southern and northern stations
At the end of the 1930s, a long corridor was built to connect the Montparnasse and Bienvenüe stations. Accordingly, the stations' names were fused to create Montparnasse-Bienvenüe on 6 October 1942. This long corridor is now equipped with moving walkways to facilitate access between the two parts of the station. The old Bienvenüe station serves lines 6 and 13, while the old Montparnasse station serves lines 4 and 12. In 2002, in an experimental move, the RATP installed a moving walkway that moved at 12 km/h, which was then termed the "fastest in the world.". The first several metres consist of metal rollers that accelerate passengers as they hold onto the handrail, because it would be dangerous to step directly onto the fast-moving conveyor. However, RATP announced in May 2009 that they would replace the walkway with an ordinary one in March 2011 in response to 'numerous customer complaints concerning safety and unreliability'.
Barrière du Maine
The southern part of the station in the Avenue du Maine was the location of the Barrière du Maine, a gate built for the collection of taxation as part of the Wall of the Farmers-General; the gate was built between 1784 and 1788 and demolished in the nineteenth century.
