Paris Métro Line 6

Line 6 is one of the sixteen lines of the Paris Métro rapid transit system. Following a semi-circular route through the southern half of the city above boulevards built along the path of the former Fermiers généraux wall of 1784–1860, it runs between Charles de Gaulle–Étoile in the west and Nation in the east. A significant part of the route is on elevated tracks.

The rails and stations of today's Line 6 were opened between 1900 and 1909, but took their current configuration only in 1942. The stretch between Étoile and Place d'Italie opened between 1900 and 1906 as Line 2 Sud. In 1907, it was made part of Line 5. The section between Place d'Italie and Nation opened in 1909 as Line 6. In 1942, the Étoile – Place d'Italie section of Line 5 was transferred to line 6, creating today's Line 6 route.

The line is 13.6 km (8.5 mi) in length, of which 6.1 km (3.8 mi) are above ground, and has been equipped with rubber-tyred rolling stock since 1974. The line is considered one of the most pleasant lines on the Métro, due to its numerous views, sometimes exceptional, of many of Paris' most famous landmarks and monuments. With slightly more than 100 million riders in 2004, it is the sixth busiest line of the network.
