The terminus of the Ligne de Sceaux was opened on the same site in 1895. Between 1973 and 1977 it was converted into Line B of the RER by the building of a 2,600 metre tunnel extending the line under the Seine to Châtelet – Les Halles and the current station was built 50 cm lower than the old station.
The station was heavily renovated in 2000. In 2009 it has engaged into large excavation work for its access to handicapped passengers, including new elevators. The construction has been stopped and apparently abandoned with no explanation. For more than two years the ticket offices have been relocated in a shelter at street level.Jardin du Luxembourg
