As an odd reminiscence, all across Europe stand vestiges of its Industrial Revolution. During the 18th century, as population kept on increasing, new techniques were developed to produce more, faster and at a lower cost. This wave of radical changes culminated in the development of railways, which gave a strong impulse to the entire economy by reducing distances. One of greatest vestiges – however unknown – of the Industrial Revolution lies in Paris. La Petite Ceinture is a dormant railroad track, a 32km path surrounding the city of light. Its construction, seen as an invitation to progress, was decided in 1852 by Napoleon III. Traffic reached its apogee with the Universal Exhibition featuring the Eiffel Tower in 1901. However, its operation wouldn’t survive the automobile revolution, nor the advent of the underground system. Indeed, urban passenger service discontinued from 1934. Oddly enough, it hasn’t gone to wrack and ruin as the infrastructure has been maintained in condition. As a river, its shores constantly change over time, but it persists. Grasses, flowers and small trees sprout from its bed. The vestige has become a boundary on the fringe of society. An intimate place, where past and modernity make their acquaintance. Mankind has influence on its own territory in many ways. Human actions such as technical paradigm shifts, or urban tissue redesign, transform our surroundings. As by-products of these transformations, residual spaces can be found in the interstices of our habitat. These are generally qualified by society as wastelands. Indeed, to rational & functional minds, residual spaces appear as wasted and as an inevitable parasites to useful and organized ones1. There is however, in this ephemeral state and in the uncertainty of its outcome, an unusual poetry. To that purpose, By the silent line focuses on a metropolitan scar carrying history: la Petite Ceinture. This long-term project - started in 2011 - is a way of maintaining the memory of a landmark and to give thought to our ability to constantly question, reconsider and transform our territory.
