This is Paris: The City of Lights.

The Paris Métro (French: Métro de Paris) has 16 lines, primarily underground, with a total route length of 213 km (133 miles).



There are 298 stations (245 of which are within the 41 square miles of the city – the densest provision of subway stations in the world).



This is Line Five crossing the Seine on the Austerlitz viaduct.

On July 10, 1900 the first line of the network, known as Maillot-Vincennes was inaugurated during the Paris World's Fair.

The system was expanded quickly at the outbreak of WW1 and the core of the Métro network was completed by the 1920s.

In the 1960s, the opted solution was finally to revive a project which had been abandoned at the end of the 19th century: joining suburban lines to fully new underground portions in the city centre. The proposed regional metro system would be known as the réseau express régional (regional express network) (RER).
