Petite Ceinture de Paris
The Petite Ceinture (“little belt”) was a railway in Paris that connected the city’s main train stations, forming a loop around Paris. It opened in 1854 and passenger service ended in 1934. Parts of the railway were still in use for freight service until the 2000’s but it has stayed mostly closed to the public until recently, when parks that follow the tracks have opened in the 16th, 15th and 13th arrondissement of Paris. There are also community gardens in the 18th and 12th arrondissement and more sections are set for development in the coming years.
