Gare d'Auber

Auber is a station on RER A in Paris. Opened on 23 November 1971 and inaugurated during a ceremony by singers Dalida and Adamo, it is one of the largest vaulted underground stations in the world.

The station comprises a main train hall with a superposed ticket hall, together with an extensive network of tunnels connecting to the neighbouring Métro stations Opéra, Havre–Caumartin and Saint-Lazare, as well as Haussmann–Saint-Lazare on RER E. It takes its name from Rue Auber, under which it is situated. This street is in turn named after the mostly forgotten 19th-century composer Daniel Auber. A complete renovation of the station was started in 2017 and is due to be finished in 2022.
