I've been in a few old abandoned warehouses with roofs in that kind of shape. They were more metal and glass than the wood pictured here, but the effect is about the same. It's too bad I didn't have a camera at the time to record some of the things I had seen. Suitable enough places to explore like this are hard to find.
Actually a place like this is extraordinary - but isn´t directly visible on this pic. This hall is over 120 years old.
This hall is part of one of the first cogeneration plant for heat and power in Europe. (And its on the area of an abandoned Tuberculosis clinic with around 60 buildings on 200 hectar)
I´ll upload a few more pics of this area - so if you like it, stay tuned and maybe watch the account :)
While there are some interesting and even historically interesting places in and around my city, most of them are just a little too dangerous to get into. And not because of trespassing and worry from law enforcement. The homeless and other vagrants occupy a good deal of those places and they're not the kind of people you want to cross paths with.
I may just have to in that case. For a while I was looking though a large archive of photos taken from derelict factories in the the Midwest of the United States, along with some from Eastern Europe and Russia. It's about as close as I can get to being in some of these really cool places.
