This summer I spent a month in Berlin writing a travel guide and this was the first building that I explored in the city. It was also the building that birthed my interest in urban exploration.
It is called the Berliner Eisfabrik. This building was an ice factory, making 1.5 metre long blocks of ice. However after running in to financial difficulty it closed down in 1995 and is currently occupied by groups of travellers who now call it home. Rather than renovating the building, there are plans to knock it down. A Wikipedia entry on the factory gives more details about the history of the building.
Some of the pictures may be a little blurry. I am not a photographer and this was on my camera phone. Plus being quite excited it was hard to keep my hands still haha.
I was terrified standing on the roof, was walking really slowly because I thought I'd fall through. Felt strange when I saw people walking around normally!
Was a really chilled place to hang out. No need to worry about police etc like it is in the UK.
