Two lost rivers from very different cities, the Adda in Bangor and the Bièvre, a little-known river that once ran through industrial areas of Paris, have some surprising connections in their history. Both rivers had been important to urban development but were culverted and re-routed in the late nineteenth and early twentieth century because of pollution and nineteenth century ideas about hygiene.
