Paris Métro Line 1 in the context of "Concorde station"

The Paris Métro, short for Métropolitain, is a rapid transit system serving the Paris metropolitan area in France. A symbol of the city, it is known for its density within the capital's territorial limits, as well as its uniform architecture and historical entrances influenced by Art Nouveau. The system is 245.6 kilometres (152.6 mi) long, mostly underground, as well as its 321 stations of which 61 allow the riders to transfer between the sixteen lines (with an additional four under construction and one in project), all numbered 1 to 14, with two extra branches, 3bis and 7bis, named such as they are former parts of Lines 3 and 7 respectively. Three of these lines (1, 4 and 14) are fully automated, and the additional four are also planned as such. Lines are identified on maps by an individual number and an associated specific colour, all part of an official palette, with the traveling direction indicated by the terminus, the last stop on each line. All trains travel from one end of the line to the other, serving every station along the way. The Paris Métro is operated by the Régie autonome des transports parisiens (RATP), which also operates part of the RER (commuter standard train) network, most of the Francilian light rail lines and many bus routes around and within Paris itself.

It is the second-busiest metro system in Europe, as well as the twelfth-busiest in the world. It carried 1.476 billion passengers in 2024, roughly 4.04 million passengers a day, which makes it the most used public transport system in Paris. It is one of the densest metro systems in the world, with 244 stations within the 105.4 km (41 sq mi) of the City of Paris. Châtelet–Les Halles, with five Métro and three RER commuter rail lines, is one of the world's largest metro stations. The system generally has poor accessibility due to its old age (established 125 years ago) and because most of the current infrastructure was built before accessibility standards emerged, with few stations retrofitted since. On the flip side, all new infrastructure and rolling stock meets current accessiblity standards, including extensions of historic lines.

The Place de la Concorde (French: [plas də la kɔ̃kɔʁd] ; lit. 'Harmony Square'), originally Place Louis XV ('Louis XV Square'), and later Place Louis XVI ('Louis XVI Square'), is a public square in Paris, France. Measuring 7.6 ha (19 acres) in area, it is the largest square in the French capital. It is located in the city's eighth arrondissement, at the eastern end of the Champs-Élysées.

It was the site of many notable public executions, including Louis XVI, Marie Antoinette and Maximilien Robespierre in the course of the French Revolution, during which the square was temporarily renamed the Place de la Révolution ('Revolution Square'). It received its current name in 1795 as a gesture of reconciliation in the later years of the revolution, although later the original name was reverted for a period. A metro station is located at the northeastern corner of Place de la Concorde on Lines 1, 8, and 12 of the Paris Métro.

Line 4 (French pronunciation: [liɲᵊ katʁᵊ]) is one of the sixteen currently opened lines of the Paris Métro, as well as one of its three fully automated lines. It connects Porte de Clignancourt in the north of Paris, to Bagneux-Lucie Aubrac in the eponymous southern suburban city, on a north-south axis across the French Capital. Held within the boundaries of the City of Paris for over a century – until its southern terminus was changed from Porte d'Orléans to Mairie de Montrouge in 2013 – the line was sometimes referred to as the Clignancourt – Orléans Line. At 13.9 km (8.6 mi) in length, it connects with all Paris Métro lines apart from the very short 3bis and 7bis branch lines, as well as with all 5 RER train lines. It also serves three of the Paris Railway stations, Gare du Nord, Gare de l'Est, and Gare Montparnasse. It is the second-busiest Métro line after Line 1, carrying over 154 million passengers in 2004.

Line 4 was the first line to connect to the south side of the River Seine, through an underwater tunnel built between 1905 and 1907. Line 4 long ran the longest-serving MP 59 rubber trains, which used rheostats to dissipate the braking power through resistance, making line 4 the hottest line in the system. Those trains were withdrawn from service on Line 4 during the course of 2011 and 2012 after 45 years (with some being in service for 50 years), yet remained another 12 years on in service on Line 11. On Line 4, they were replaced by the MP 89 CC stock transferred from Line 1, right after its automation.

Paris Métro Line 14 (French: Ligne 14 du métro de Paris) is one of the sixteen lines currently open on the Paris Métro. It connects Saint-Denis–Pleyel and Aéroport d'Orly on a northwest–southeast diagonal via the three major stations of Gare Saint-Lazare, the Châtelet–Les-Halles complex, and Gare de Lyon. The line goes through the centre of Paris and also serves the communes of Saint-Denis, Saint-Ouen-sur-Seine, Clichy, Le Kremlin-Bicêtre, Gentilly, Villejuif, Chevilly-Larue, L'Haÿ-les-Roses, Thiais and Paray-Vieille-Poste.

The first Paris Métro line built from scratch since the 1930s, line 14 has been operated completely automatically since its opening in 1998, and the very positive return of that experiment motivated the retrofitting of Line 1 for full automation. Before the start of its commercial service Line 14 was known as project Météor, an acronym for MÉTro Est-Ouest Rapide.

The Place de la Concorde (French: [plas də la kɔ̃kɔʁd] ; lit. 'Harmony Square'), originally the Place Louis XV ('Louis XV Square'), and later the Place Louis XVI ('Louis XVI Square'), is a public square in Paris. Measuring 7.6 ha (19 acres) in area, it is the largest square in the city. It is located in the 8th arrondissement, at the eastern end of the Champs-Élysées.

The square was the site of many notable public executions, including Louis XVI, Marie Antoinette and Maximilien Robespierre in the course of the French Revolution, during which it was temporarily renamed the Place de la Révolution ('Revolution Square'). It received its current name in 1795 as a gesture of reconciliation in the later years of the revolution, although later the original name was reverted for a period. A metro station is located at the northeastern corner of Place de la Concorde on Lines 1, 8, and 12 of the Paris Métro.

Bastille (French pronunciation: [bastij] ) is a station on Line 1, Line 5 and Line 8 of the Paris Métro. Located under the Place de la Bastille and near the former location of the Bastille, it is situated on the border of the 4th, 11th and 12th arrondissement.

Charles de Gaulle–Étoile station (French: [ʃaʁl(ə) də ɡol etwal] ) is a station on Line 1, Line 2 and Line 6 of the Paris Métro, as well as on Île-de-France's commuter rail RER A. It lies on the border of the 8th, 16th and 17th arrondissements of Paris. Originally called simply Étoile, after its location at Place de l'Étoile, it took on the additional name of President Charles de Gaulle in 1970.

La Défense station (French pronunciation: [la defɑ̃s]) is a station of the Transilien (Réseau Saint-Lazare) suburban rail lines, RER commuter rail network, Paris Métro, as well as a stop of the Île-de-France tram network. In the future, Paris Metro Line 15 of Grand Paris Express will pass through here, making it a huge railway hub. It is underneath the Grande Arche building in La Défense, the business district just west of Paris. The station is the western terminus of Métro Line 1 and connects the RER A line to the Métro Line 1 station since 1992, the Line 2 tramway since 1994 and SNCF (Transilien) train station. It is also attached to a major shopping centre. There are over 25 million entries and exits each year. A temporary special SNCF service began in April 1959 (1959-04) to serve the newly-built Centre of New Industries and Technologies (CNIT); the RER entered service on 19 January 1970 (1970-01-19). The RER E station built under the CNIT opened on 6 May 2024.

Highlights on the surface nearby include the monumental Grande Arche, skyscrapers that host the headquarters of important French and foreign companies, and works of urban art such as Le Pouce by César Baldaccini. From the central esplanade the Arc de Triomphe can be seen further down the Axe historique. Until May 2004, this part of La Défense hosted an information centre of the European Union managed by the European Parliament. Like the district it serves, the station takes its name from the 19th-century statue La Défense de Paris, commemorating the Franco-Prussian War.
