Petite Ceinture in Paris 14e arrondissement, Linear park on former railway line in Paris 14e arrondissement, France.

The Petite Ceinture in the 14th arrondissement is a narrow green corridor laid on the ballast of a disused railway line. Its gravel path follows the old rails past retaining walls, a short tunnel and stretches of self-sown vegetation, with the track bed sometimes sunk below street level and sometimes level with the surrounding buildings.

The section through the 14th arrondissement opened in 1867 as part of the Chemin de fer de Petite Ceinture, a ring line linking Paris's main stations. Passenger service ended in 1934, and freight continued until the line was decommissioned. Since 2013, the City of Paris and the SNCF have opened stretches as walking routes, with this segment accessible since 2019.

The Petite Ceinture du 14e is a listed railway heritage site: its 1867 line, viaducts and tunnels are protected, and the ballast, rails and signals remain in place. Since 2013 the association Espaces has opened the section to the public, and street artists paint on the retaining walls, so a walk here shows both 19th-century engineering and present-day graffiti.

Access points exist near rue de la Tombe-Issoire and rue de la Légion Étrangère, but some sections are only open during guided visits or specific hours. The route is narrow and unpaved in places, with steps and uneven ballast, so it is not suitable for strollers or wheelchairs. Check local opening notices before setting out.

The line's deep cutting left the old track bed below street level, so the corridor stayed largely undisturbed after the last trains stopped. That isolation let plants and animals settle along the rails, and today the route forms a continuous green link between the surrounding blocks of the 14th arrondissement.
