Just 15 kilometres from the city centre, these primitive landscapes seem to be from a different land altogether, but this is a waterway that continues to steadily flow towards Paris. One hundred years ago, it still managed to slide its way through the city walls and on headfirst into the Seine, but by the time it arrived at that point it was a pestilent soup rather than a pristine stream.
In and around Paris it was a river that was put to work, primarily in the tanning industry. After centuries of abuse, it had become a dead channel, clogged with blood and dyes. At the beginning of the 20th century, the city authorities decided that they had had enough, covered over the stream and directed it away from the Seine and into the city's sewerage system.
Walking alongside the Bièvre in these timeless locations it is hard to imagine that this is one of the only rivers in the world that has no natural discharge. Is this a picture of how it once was along its entire length, up to what became Paris at its meeting point with the Seine?
Beyond the boundaries of Paris it has continued to thrive, and a project was recently announced to open up more stretches to visitors. Certain groups still militate for an uncovering of the river along its entire length, but in reality Paris has today developed away from one of its natural sources.
It is impossible to wind back time, but thankfully it is sometimes still possible to visit the past.
