Cité station lies underneath the Île de la Cité, one of two islands on the Seine within the historical boundaries of Paris. In relation to the rest of the city, it lies within the 4th arrondissement, near Kilometre Zero, the official geographical and historical centre of Paris. The only station on the Île de la Cité, it lies near many famous landmarks, the most famous being the Cathedral of Notre Dame. To the west are the Sainte-Chapelle chapel and the Palace of Justice, while Notre Dame and the Hôtel-Dieu are to the east.
The station was opened on 10 December 1910 on the section of the line under the Seine between Châtelet and Raspail. This section of the line had actually opened on 9 January 1910 but trains passed through the station without stopping until the December of that year.
Tunnels were later built linking the station to the nearby Prefecture of Police of Paris and the Palais de Justice. However, for security reasons, these tunnels have now been closed for more than thirty years.
