100 years of the metro (1900-2000)
To enable Parisians to easily find access to the stations, exterior surrounds mark the metro entrances using tulip poles integrated into Hector Guimard’s Art Nouveau balustrades.
Over the years, these masts diversified. From the beginning of the century, the Val d’Osne appeared, which was still very elaborate.
Designed by the architect Dervaux in the 1920s, the candelabra installed here is placed on a wrought iron surround which blends into the urban environment. Some are marked Pedestrians, to invite them to cross the street using the underground passages. Topped with a luminous globe, they indicate the stations to night owls who can rush there until 1 a.m. for the last metro.
