With the Manuelskotten, the city of Wuppertal owns a special kind of industrial history monument. Nestled in the narrow valley of the Kaltenbach, the Kotten is halfway between Cronenberg and Kohlfurth. Today, the Manuelskotten is not only the last waterwheel-powered facility on this stream, but in the entire urban area of Wuppertal. The various types of power engines that are gathered under its roof make it unique in the entire region. With its waterwheel, steam engine, diesel engine, generator and electric motor, it provides an overview of the history of energy generation. The Manuelskotten is still used for commercial grinding and sharpening. Due to the largely unchanged technology and minimal interventions in the surroundings of the Kotten, an authentic situation can thus be presented.
Since autumn 2017, the Manuelskotten has a new attraction: an exhibition on wet grinding, which can be visited on the upper floor (during the opening hours of the Kotten and by appointment). Informative texts, historical visual material, archives and numerous exhibits from the extensive collection provide exciting insights into the history of the Manuelskotten and wet grinding. They tell about the people behind the grindstones, about their everyday work and working conditions. The special hand movements and challenges of the craft are illuminated as well as Cronenberg's importance as a production site for high-quality tools. The collection comprises more than 500 exhibits. Most of them are housed in thematically arranged drawers. These invite visitors to discover, read up on and delve deeper.
The exhibition was funded by the Landschaftsverband Rheinland.
