The Technology Gallery is located in Kassel, and it is one of the few factories that have preserved large parts of the original materials. The historical period extends from the construction of the Museum's first hall in 1870 AD to the stage of expansion at the turn of the century. The plant is a typical example of both architectural and mechanical engineering - one of the oldest production facilities for old locomotives in Germany that has been preserved as a collection. It aims to collect products, technologies and innovations from the city of Kassel and northern Hessen, to display and place them in a historical context. This also includes holding lectures and discussions.
