Access

The station is famous for one of its entrances, created by Hector Guimard, registered as a historic monument by the decree of 12 February 2016^[4] and completely restored in October 1999 for the celebrations of the centenary of the Paris metro. It has a total of four metro outlets:

• entrance 1 - Boulevard Lannes, consisting of a fixed staircase diverging into two other staircases, each decorated with a Dervaux candelabra, leading to Place du Paraguay at the right of nos. 81 and 83 of Avenue Foch;
• entrance 2 - Avenue Foch, consisting of a fixed staircase also decorated with a Dervaux mast, located north of the odd median of this avenue;
• entrance 3 - Boulevard de l'Amiral-Bruix, consisting of a fixed staircase topped with the only original Guimard kiosk with a canopy in the Art Nouveau style, located opposite the Place des Généraux-de-Trentinian on the even side of the Avenue Foch;
• entrance 4 - Avenue Bugeaud, consisting of a fixed staircase allowing only an exit and equipped with a more modest Guimard entourage (also classified as a historic monument), leading to the angle formed by this avenue and the odd alley of Avenue Foch, to the right of no. 77 of the latter.

Platforms

Porte Dauphine is a station with a particular configuration. It is made up of two divergent half-stations framing a very tight turning loop, only thirty meters in radius, according to its original racket layout, which is the only network to be fully preserved. The arrival half-station to the north has two central tracks, the northern one serving a single lateral platform, while the southern one, a dead-end to the west and without a platform, is used for the train depot and runs technical rooms. The half-station for departure is made up of two tracks separated by an island platform, that of the north a dead-end, in the west, also serving as depot. The vault is elliptical in both cases.

The station is also one of only two in the network, with Porte de Vincennes on line 1, to have preserved its original decoration in flat cream-colored tiles, which is one of the experimental decorations tested in 1900 before selecting the famous bevelled white tile for other parts of the network.^[5]: 149 This tiling covers the walls, the vault and the tympans. Lighting is provided by a tube strip in each half station. The platforms are free of advertisements and the name of the station is inscribed on enamel plaques, in capital letters or in Parisine font depending on the location. The boarding platform has benches made of wooden slats painted red.

Architecture

The station contains one of the three remaining "dragonfly" roofed Métro entrances by Hector Guimard (1867–1942), the Art Nouveau architect who was originally commissioned by the Compagnie du Métropolitain de Paris (CMP) in 1899 to design the entrances for the Métro stations. It is the only roofed entrance that is original, not reconstructed, and on its original site. It was restored in 1999.^[6]: 43

Other connections
