In addition to the big mansion in Schloss-Wolfsbrunnenweg 33, covering a surface of over 1800 m², a second building was erected not far away in Schloß-Wolfsbrunnenweg 46. It served as a lodging for Bosch´s drivers and as a garage for Bosch´s cars, including the vintage brands Maybach and Horch.

In this "Garagenhaus“ the Carl Bosch Museum in Heidelberg was inaugurated in May 1998. This technical museum shows the most interesting and exciting highlights of the life of Heidelberg´s Nobel prize-winner Carl Bosch (1874-1940) on a surface of more than 300 m² and two outdoor areas.

The topics range from the development of chemical engineering to IG Farben´s role during the Third Reich. The development of high-pressure technology from its beginnings in the laboratory to the creation of gigantic industrial complexes is as well reconstructed as their political and economical effects are documented. The exhibition consists of eight different sections.
