Crusauer Kupfer- und Messingfabrik, Industrial museum in Kupfermühle, Harrislee, Germany.
The Crusauer Kupfer- und Messingfabrik occupies three converted industrial buildings where metal has been processed for centuries. The facility shows the complete process of copper and brass manufacturing, from raw materials to finished goods, and sits near the border with Denmark.
The facility started as a hammer mill in 1600 through a royal Danish initiative and grew into one of Northern Europe's major copper and brass producers over the following centuries. Ownership changed multiple times, and production adapted to evolving market demands throughout its long operation.
The site preserves worker housing from different periods that developed alongside the factory buildings. Visitors can see how laborers and their families lived, and how closely their daily lives were tied to production cycles.
The museum operates from May through October on weekdays and weekends, with weekend-only hours from November through April, always between 13:00 and 17:00. Wear comfortable shoes since the exhibition spreads across multiple buildings with considerable walking space.
The facility preserves original machines and workshops showing metal processing from hand-operated hammers to mechanized systems. Visitors can trace how working methods evolved from the 17th century until the factory's closure.
