Petite Ceinture du 12ème

The Petite Ceinture of the twelfth arrondissement was once a vital artery for the industrial life of Paris. Built starting in eighteen fifty-two, this circular railway line was engineered to link the city's major train stations and supply the massive fortification walls that once ringed the capital. For decades, it facilitated the movement of goods and passengers, acting as a crucial loop for trade before the rise of the Metro eventually rendered its circular service obsolete.
