Technik-Museum Kassel

In the page's words:

Museum treasures from heavyweight to tiny are presented in the former factory halls and span a unique arc over more than 300 years of Kassel's technological history. The exhibition bears witness to the unparalleled diversity of North Hesse's industrial culture as well as to important personalities and technical creativity: from historic fire engines and solar cars to flame-eaters and machine tools. The collection also includes magnetic levitation technology with the Transrapid TR05, electrical energy technology and communications and media technology.
