Abandoned Brewery.

I'll have to go back to this one as soon as possible.
Originally only a nice-to-have opportunity for exploration, the old "Bärenquell Brauerei" (Bearpond Brewery) proved to be a true jewel.
The brewery, the entire complex is huge! It consists of at least twelve buildings, for exapmle the residence of the officers, the administration offices, the beer storage with the cooling tower and a lot more.
To give an impression of the size, here's a picture of the southern buildings:

As you can see, the thing is big. Really big. So big that I think I'll need at least a day to fully explore it, and I hopre that day is soon.
Anyway, with about an hour of daylight left, here are some impressions from the brewery.
