The Halbachhammer was a donation from Gustav Krupp von Bohlen und Halbach to the city of Essen. Originally located in Weidenau an der Sieg, the listed building is now situated in the western part of the forest park which was created as a permanent installation and donated to the city of Essen for local recreation by Margarethe Krupp in conjunction with the construction of the Margarethenhöhe. During the summer time, on the first Sunday every month, the technical monument of the Ruhr Museum is demonstrated in show events.
