City gates of Paris in the context of Porte de Choisy (Paris Métro)

Porte de Versailles (French pronunciation: [pɔʁt də vɛʁsɑj]; lit. 'Gate of Versailles') is a station on Line 12 of the Paris Métro, a stop on tramway Line T3a, as well as the southern terminus of tramway Line T2 in the 15th arrondissement. It is named after the Porte de Versailles, a gate in the 19th-century Thiers wall of Paris, which led to the city of Versailles.

Balard (French pronunciation: [balaʁ]) is the southwestern terminus of Line 8 of the Paris Métro in the 15th arrondissement of Paris. Since 16 December 2006, it has also been a stop on tramway T3a as part of the initial section of the line between Pont du Garigliano and Porte d'Ivry. The station is named after Place Balard, itself named after Antoine-Jérôme Balard (1802-1876), a French chemist and the discoverer of bromine. Among the stations serving the Boulevards des Maréchaux along the former gates of Paris, it is the only one not called Porte de…, though it serves the Porte de Sèvres.
