100 years of the metro (1900-2000)
The lead architect of Art Nouveau, Hector Guimard was chosen in 1899 to design the accesses to the stations.
But in 1900, when the metro opened, its decorative audacity shocked the Parisians. The “Metropolitan” spelling is said to lack readability, and the tulip masts which serve to indicate access at night are monster eyes.
As early as 1902, station access was ordered from less contested architects. In 1913, the installation of Guimard metro outlets was stopped, and during the renovation of stations in the 1960s, several of them were destroyed and replaced by modern surroundings.
But today, new molds have been made to restore the Gulmard accesses classified as Historic Monuments.
