The 163-meter-high chimney was supposed to be demolished after 40 years of existence. The company that owned the chimney didn't want to say goodbye to this colossus just like that, so there was an opportunity to beautify it a little before the demolition day.
The motif is based on the idea of "returning to nature". At the bottom is a huge cauldron with a human face (some residents took the BRANDL chimney as a being), from which pipes off all kinds of shapes. All eventually becomes a forest at the end. Steam then escapes from the pipe in the form of ghosts, a metaphor for departure to the other world.
