View of Wipperkotten Grinding Mill

There is a book and a movie (broadcast on WDR) titled: "The Wupper - Amazon in Bergisches Land". The Wupper lives again and is full of surprises on its 116 kilometers in length. The untamed waters offer not only countless picturesque motifs, but above all, there are a variety of fantastic plant and animal species to discover on a journey from the source to the mouth. Almost like the South American relative, the Amazon.

Anyone passing the Kotten without looking in has missed a real gem of Solingen's industrial history and the encounter with the last Solingen grinders.

Once considered the Wupper as the most industrious river in Germany. Their flow provided countless craft and industrial companies with energy. Then she was reputed to be the "dirtiest river in Germany". Wastewater caused it to degenerate into the sewer of the region. Today, after successful renaturation, it is once again the lifeblood of the Bergisches Land with an unimaginably species-rich flora and fauna.
