I explored a room with switching cabinets but the room smelled terribly oily, leaving a bitter tast in my mouth. Not very healthy presumably.
Going one floor up again. There was less glass on the floor, probably the windows are harder to hit so far up, but the floor wasn't much cleaner. It was covered in pigeon dung, with the occasional dead pigeon in between. I unwantingly scared some pigeons away, some loosing some feathers flying through the broken windows.

This papery stuff was lying all about the factory, but I still don't know what it is. And is that a sleeping bag? Can't remember seeing it when I took this picture.

Some storage rooms had wooden floors, so I didn't explore much. Someone else had obviously.

Wasn't me.

This was the only floor to feature some more colourful graffiti

A small office overlooking the floor

The small office had a storage room below it, but it had the same rancid oily smell so I quickly left again. The office itself had been used as some kind of clubhouse or boozing party, considering the number of bottles on the desk.

An assortment of bottles.

But than again, reading the poetry on the wall:
"Das Leben kann ? und gleichzeitig so grausam sein!
Ich hasse mein leben doch (?) habe angst es zu enden."
(Live can be ? and at the same time be so cruel!
I hate my live but I'm scared to end it.)

And more with the same emotions.
When I shot a picture of the writings on the wall I thought they were just stupid love poems, but now when I try to decipher them from an unclear photo I understand there is more to them then I thought.

So maybe not a boozing party.

Going another floor up, I found some impressive fans.

I added my flashlight as a measure of scale. Picture was made from 2 photos, because I couldn't step back any further.

Another fan, diameter approximately 2.5 metres.
