The station opened on 19 October 1904 as Saint-Maur. It changed its name to Rue Saint-Maur on 1 September 1998 in order not to confuse it with a station on the RER A in the community of Saint-Maur-des-Fossés.
The station is named after Saint Maurus, a Benedict monk who saved the life of Saint Placide.
It is situated in the 11th arrondissement. It is served by the metro line 3.
The main entrance to the station is in the art nouveau style. The "Metropolitain" sign arches over the stairs. The posts are flower-shaped with red lights.
On the ground underneath the lampposts a wide white row of raised plasticised circles to mark the top of the stairs.
Five round lamps are placed over the entrance at ground level. They are in green metal holders.
The fence is made of large cast-iron panels designed by Hector Guimard. They too are in the art nouveau style showing flowing forms based on nature.
The panels are painted matt green.
Station sign and lamp over a map of the metro network.
The station name is spelled in green on a yellow background with an art nouveau typeface.
The second entrance goes straight to the platform.
It has a modern panel with advertising, the station name and the number of the line serving it.
Three round lamps are placed over the entrance at ground level. A sign above the lamps indicates that the entrance is only for valid ticket holders.
On top of the stairs is a row of grey nobbed tiles, but it is not highlighted in white.
Metal handrails have been fixed to both side walls.
The iron fence is plain green, with bars of different lengths.
Steps to the ticket hall. At the right is the machine to buy tickets and recharge the Navigo.
The two silver exit doors open in the middle.
Corridor from the secondary entrance to the platform. The curved ceiling is painted white.
Some advertising boards have white ceramic borders, but most are in separate frames mounted on the wall. They are lit from behind.
The border tiles are green flowers.
The curved ceiling of the platform is tiled. The tiles reflect the light.
A long row of orange plastic chairs is mounted on orange tiles. The lights are in matching orange metal boxes above the edge. This style is called Andreu-Motte.
The advertising behind is in metal frames.
The edge of the platform is marked in white, with no additional yellow line. A row of about 20 cm wide nobbed tiles has been added to warn sight-impaired travellers of the edge.
The station name is printed in white upper and lower case letters on a blue plastic sign.
Entrance to the platform is from the end.
The tiles in the arch are orange.
The walls are curved all the way to the ground. So the advertising boards are curved as a result.
