The original station on 21 April 1908 as part of the first section of the line from Châtelet to Porte de Clignancourt to serve Les Halles (the old markets). The station was rebuilt in 1977 about ten metres further east to interchange with the new Châtelet - Les HallesRER station. This RER station is connected by underground corridors to the Métro station Châtelet, and Les Halles is therefore also connected with Châtelet. The Métro Line 4 is the only line that serves Les Halles, and in addition it also serves the Châtelet station.
The walking distance from (Line 4) at Les Halles to the far end of Châtelet (Line 7) is about 900 metres (3,000 ft).
Les Halles serves the underground shopping center Forum des Halles. One of the floors of the Forum des Halles contains the Métro station.
