Europe, France, Paris

Denfert-Rochereau is a station on the Paris Métro and RER systems. The RER station was previously a terminus of the Ligne de Sceaux, a surface suburban railway. It was rebuilt as an underground station, though the original station building survives and has been restored. The station opened on 24 April 1906 with the opening of the extension of line 2 Sud from Passy to Place d'Italie. On 14 October 1907 line 2 Sud became part of line 5. On 12 October 1942 the section of line 5 between Étoile and Place d'Italie, including Denfert-Rochereau was transferred from line 5 to line 6 in order to separate the underground and elevated sections of the metro (because the latter were more vulnerable to air attack during World War II). The line 4 platforms were opened on 30 October 1909 when the southern section of line 4 was opened between Raspail and Porte d'Orléans. Its name refers to Place Denfert-Rochereau, named for the 19th-century general Pierre Philippe Denfert-Rochereau, who led the resistance of Belfort to a siege during the Franco-Prussian War. The first part of the name is identical in pronunciation to its former name of Place d'Enfer ("Place of Hell"). It is the location of the Barrière d'Enfer, 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 is one of only four of the 55 gates with any surviving remains.
