Inauguration of Paris Métro Line 1

The Paris Métro's inaugural Line 1 began operations on May 29, 1900, just in time for the Exposition Universelle. Designed by Fulgence Bienvenüe with elegant Art Nouveau entrances by Hector Guimard, the line featured innovative electric traction and cut-and-cover construction through the city's dense urban core. It quickly transformed daily life for Parisians, easing congestion and setting the standard for modern rapid transit systems worldwide. The Métro's success influenced subway designs in cities from London to New York and remains one of the busiest lines in the network today.
