There is some kind of magical feeling to abandoned spaces. A few years ago they we visited abandoned factory in Zagreb to collect some scraps for decoration of an event we were organizing. Unfortunately I have no photos of the factory itself, but that old factory fully demonstrated the power of nature. Branches and roots dug through the walls and crashed most of them. Branches even destroyed the brick roof to extent of completely removing it. It is hard to put in words power of nature you feel when you are in that factory.
