The station opened on 5 November 1910.
It is situated in the 10th arrondissement. The station takes its name from the nearby rue Château-Landon, which in turn was built on land owned by a family from the Château-Landon area.
It is served by the metro line 7.
The platform has been built on unstable ground, so a centre wall has been added to support the site. Some arched breakthroughs have been added as well.
The walls and vaulted ceiling are tiled with flat white horizontal tiles.
The red lights are in the Ouï-dire style - the brackets look like scythes.
Access to the platforms is from the end.
The station name is printed in white mixed case letters on a blue sign.
Below the sign is a framed map of the train, metro and tram network.
The advertising boards on the supporting central wall are framed with red ceramic tiles.
The electronic display shows the present time and information for the next four trains of the line 7. The line separates further on, so the waiting times for the next two trains for each branch are shown. The next train due is going to Villejuif, the blue branch line. This is highlighted by the blue triangle.
Red plastic seats are mounted to red metal arches fixed to the ground. There are also some steel benches covered in red plastic foil and fixed to the wall.
The central supporting wall is quite thick. The entrance to the arches have been fitted with gates.
