An old diesel power plant in Germany. It was a part of some sort of factory, but I couldn't find any info about it. Could have been a textile factory. Many of the buildings were repurposed - ateliers and small workshops from what I could see. The area is wide open but the access into the building was a tight squeeze for some people from our group. Inside were two diesel engines and one thing half in the ground that could have been an engine as well or something else. The control panels were nice old-school marble ones.
