Oriented along a north-south axis, it is interspersed between the Jussieu and Censier - Daubenton metro stations.

In the direction of Mairie d'Ivry and Villejuif - Louis Aragon, it was preceded by a connection with line 10, which was in commercial service for a year, from 1930 to 1931, when this line had as its terminus Porte de Choisy.

This former arrangement can still be seen at the north of the station where a non-revenue track diverges on the left, leading to Cardinal Lemoine (now on Line 10).

Nearby are the Jardin des Plantes (botanical garden), the Roman remains of the Arènes de Lutèce and the Rue Mouffetard, a street with restaurants and a lively street market.

These fittings are combined with the bevelled white ceramic tiles that cover the side walls, the vault, the tunnel exits and the outlets of the corridors.
