Gambetta is a station of the
Paris Métro. It serves
Line 3 and is the southern terminus of
Line 3bis. It was opened on 25 January 1905 when the line was extended from
Père Lachaise and was the eastern terminus of the line until 27 November 1921, when the line was extended to
Porte des Lilas. In 1969, the former
Martin Nadaud station—which was only 232 metres west of
Gambetta—was combined with
Gambetta by linking
Martin Nadaud's closed platforms with
Gambetta by tunnel. On 23 March 1971 the line to
Porte des Lilas was separated from line 3 and became
Line 3bis. The beginning of the old tunnel to
Porte des Lilas now connects the platforms of lines 3 and 3bis. On 2 April 1971 line 3 was extended to
Gallieni.
