Some weeks ago, I was at an historically important place in the Ruhrgebiet, Germany.
The boat lift in Henrichenburg was very important for the transport of raw materials, especially coal. It doesn’t work like a normal lock, 70 years ago, it was a technical revolution. Now, it ’s a museum and you can learn how the mechanical masterpiece worked. There are also some interesting loan exhibitions, sometimes artwork, but basically interesting things about the past in the Ruhr area.
