Most of the factory next to the Barbed Wire Villa has been demolished since production ended in the 1980’s, but several buildings in various states of decay were still around.
The area of the main factory was now a metal recycling plant. But on the opposite side of the road from it were two other buildings. The other one was a collapsed factory, which I was unable to photograph. The second one was this:

The building had originally been larger. According to old maps, it was both deeper and multiple times wider towards the right side of the picture. Unfortunately I was unable to take a closer look. The yard was overgrown and full of metal scrap and I wasn’t wearing proper shoes.
Guess twice, if I will return or not.
