Bièvre

The Bièvre is a 36 kilometre-long river that flows into the Seine in Paris.

During the 18th century, the Bièvre was of great economic importance, with numerous tanneries and workshops built alongside its banks. As a result, the river became severely polluted.

Nowadays, the Bièvre is virtually out of sight, concealed by the urban landscape.

Trivia
