9, pl. Saint-Michel Pl. Saint-Michel × boul. Saint-Michel pl. Saint-Michel × quai Saint-Michel 15, pl. Saint-André des Arts 5th arrondissement of Paris Île-de-France France
The station was opened on 9 January 1910 as part of the connecting section of the line under the Seine between Châtelet and Raspail. It is named after the Boulevard Saint-Michel.
Architecture
Like nearby Cité, Saint-Michel features a pioneering construction technique, made necessary by the proximity of the Seine. The station comprises three steel caissons – one for the train hall and two for access at each end – which were assembled at the surface and then lowered into place.[1]
The platforms are 118 metres long, more than the standard length on the network.[1] This allows it to potentially handle eight-car trains, however, due to the other stations having an average of 100-meter platforms (excluding Cité, which has 110-meter platforms), and the Line's ongoing process for automatic operations, the trains in the Line 4 will be limited to six-car trains.
