The Montmartre funicular is a two-car electric incline railway that transports passengers from the base of the Montmartre butte up to the terraces of the Sacré-Cœur basilica (and vice versa). It is operated by the RATP, the Paris transport authority, so subway tickets and passes are valid (fare is one individual ticket per direction).
The original funicular opened on the eve of Bastille Day, July 13, 1900 - exactly 108 years ago today - although the present day electrical funicular dates from 1991. Each car makes the ascent or descent in 90 seconds and saves its 60 passengers more than 300 steep steps.
The first Montmartre funicular was water powered, using a system of cisterns that were filled or emptied in order to move the cars, as a function of passenger load. In 1935, the system was converted to electricity.
