Hi, I present you couple of pics about Museum Neues Weimar and Goethe-Museum. In Museum Neues Weimar you can see many things about the time, as the art and architecture had been changed. Change to secession / art noveau and at least to Bauhaus. Thank to macen Harry Graf Kessler and Henry van de Velde.
The Goethe Museum is also worth to visit. He is known mainly about his literature works, such Faust, but he was a botanist, geologist, had made experiments with colours.
