Croix Rouge was originally the end station for Line 10, closed before WWII. The author of Pridian.net contends that it’s the only station in the system that hasn’t been repurposed in some way, even for non-passenger usage like Porte Molitor.
“The station has never been reused by the RATP (Parisian metro authority) as there is no easy access for RATP staff or clandestine visitors alike. The advertisements, seats and even the station masters booth can still be found on the platform…All that signals the existence of the station are two grills on the footpath. Take a close look and and you can catch a glimpse of the white tiles on the walls of the former station.”
