Châtelet is a station on lines 1, 4, 7, 11 and 14 of the Paris Métro
in the centre of medieval Paris and the 1st arrondissement.
The station is made up of two parts connected by a long corridor: Lines 7
and 11 under the Place du Châtelet and the Quai de Gesvre
(site of the original medieval river port of Paris), next to the Seine;
Lines 1, 4 and 14 towards Rue Saint-Denis and the Rue de Rivoli.
Châtelet is connected by another long underground corridor to the
southern end of the RER station Châtelet - Les Halles, the northern end
of which is again connected to the Métro station Les Halles.
The walking distance from Line 7 at Châtelet to the RER lines at
Châtelet - Les Halles is circa 750 metres.
The station was opened on 6 August 1900, three weeks after trains
began running on the original section of line 1 between Porte de Vincennes
and Porte Maillot on 19 July 1900. The line 4 platforms were opened on
21 April 1908 as part of the original section of the line from Porte de Clignancourt
to Châtelet.
The Line 7 platforms were opened on 16 April 1926 as part of the line's extension
from Palais Royal to Pont Marie with the name Pont Notre-Dame-Pont au Change.
It had no direct connection with Châtelet. On 15 April 1934 a connecting corridor
was opened to the platforms of lines 1 and 4 and the line 7 station was renamed.
The line 11 platforms were opened near the line 7 platforms on 28 April 1935 as part of the original section of the line from Châtelet to Porte des Lilas.
On 9 December 1977 the Châtelet - Les Halles RER station was opened with a
connecting corridor with a moving walkway to Châtelet.
The line 14 platforms were opened near the line 1 and 4 platforms on 15 October 1998
as part of the original section of the line from Madeleine to Bibliothèque François Mitterrand.
On 7 and 8 March 2009 the line 1 platforms were restored during the automation of line 1,
including the installation of platform screen doors.
It is named after the Place du Grand Chatelet which was demolished in 1802
