The Porte des Lilas-Cinéma station is one of the world's most popular film sets. This ghostly station, closed to the public since 1939, hosts around 5 or 6 feature films every year. Amélie Poulain, John Wick and Les Femmes de l'ombre have all been filmed here. RATP rents out this customizable station for between €15,000 and €18,000 a day, generating nearly €200,000 in annual sales. The advantage? Crews can completely modify the set, change the advertising posters and even use vintage trains to suit the needs of the script. [Read more]

The Arts et Métiers station on lines 3 and 11 plunges us into the world of Jules Verne's Nautilus. In 1994, to celebrate the bicentenary of the Conservatoire National des Arts et Métiers, Belgian artist François Schuiten transformed the station into a real submarine. Riveted copper plates, brass portholes, ceiling gears and wooden seats create a unique retro-futuristic atmosphere. The portholes reveal models of historic inventions, paying homage to the Musée des Arts et Métiers. The renovation is inspired by 'Twenty Thousand Leagues Under the Sea', transforming every passage into an extraordinary voyage. [Read more]

Paris-Saint-GermainParis-Saint-GermainParis-Saint-GermainParis-Saint-Germain Did you know? A secret station hides beneath the Parc des Princes
Beneath the Parc des Princes lies a little-known ghost station: Porte Molitor. Built in 1923 on lines 9 and 10, this station was intended to facilitate access to the stadium during Paris-Saint-Germain matches. However, when the Parc des Princes was expanded in 1932 and its capacity doubled, the station proved too small to handle the crowds. For safety reasons, it was never opened to the public, nor were there any subway entrances. Today, it serves as a siding for the Auteuil loop. [Read more]

The Place des Fêtes station on lines 7bis and 11 hides a wartime secret. Built in 1935, it was originally designed as an air-raid shelter to protect the civilian population from bombardment. Located 27 meters underground in a densely populated working-class district, it features airtight doors, a filter chamber to purify the outside air, and swing doors in the corridors. Its impressive 256-step escalator is the largest in the RATP network. At the time, the press described it as 'the biggest and safest shelter in the world'. Maison Blanche station shared this defensive function. [Read more]

The metro's famous white tiles weren't chosen at random. Art Nouveau architect Hector Guimard designed the beveled tiles to reflect light. At the time, lighting was limited to a 15-watt bulb every 5 meters. Boulenger, a Paris-based company specializing in ceramics, carried out this huge project. This 'metro tile' has become so emblematic that it now adorns bars, restaurants and bathrooms the world over. [Read more]

Why don't the metro and RER run in the same direction? This curiosity has its origins in the history of European railroads. RER trains always arrive on the right-hand side of the platform, as they run on the left-hand track, following the British railway tradition imported to France in the 1830s. The metro, on the other hand, arrives on the left-hand side of the platform, as Paris wanted to distinguish itself from the traditional railway system in 1900. The City of Paris deliberately created small-scale rolling stock running on the right-hand side to prevent the railways from mixing their tracks with the Paris metro. [Read more]
