It’s Full Of Ghostly Metro Stations
It should come as no surprise that the 400+ station Paris metro system contains several hidden gems. One of the interesting facts about Paris is ghost stations are those of the Paris Métro that are no longer in use for commercial purposes and have been closed to the general public. Many stations on the Paris Métro have been made inaccessible and sit vacant for historical or financial reasons, giving Parisians a feeling of mystery.
When France entered World War II in September 1939, the bulk of these ghost stations were shuttered, and some of them have remained shuttered ever since. As the network developed, some of them were recycled or entirely disappeared. Two stations were built but never used; they are still unavailable to the general public. Three more were planned but never had a Métro line to serve them.
