Because of strict building and zoning laws implemented during Haussmann’s beautification of Paris, many areas of the city are extremely well-kept. Enter: La Petite Ceinture, or ‘The Little Belt,’ an abandoned railroad track that circles around the edge of Paris, and which has stood unused for the past 80 years. A playground for graffiti artists, most of the flat surfaces along the track (including the backs of some apartment buildings, to the owners’ chagrin) are completely covered with paint. For art-lovers whose taste is a bit different than the classic oeuvres one might find in the larger and more traditional museums in Paris, La Petite Ceinture is a must-see. Below are our favorite shots of what you will find along the empty tracks.
