concern for the environment. and in our series underground europe we visit an eerie stop to rainy and lake in southern switzerland. dividend or the turning point that's the term that germans used to refer to the fall of the berlin wall in 1909 an event that mend the end of east germany and clear the way for the country's reunification of artists who had found a way to co-exist with the communist system and opened a vast new world of possibilities at the same time however it up ended everything about their creative motivation and their lives well 30 years on an exhibition in light 6 looks at the art that was produced during this turbulent period. doris siegler doesn't see herself as someone who can see into the future but what the leipsic artist painted just a year before the fall of the wall did come to pass people peacefully demonstrating with candles crossing a border bridge as well as nothing it was spring 980 s.

and i explain it to myself as a type of wish fantasy for change and also one of personal change. in this personally an awful mess. siegler is one of more than a 100 artists whose work documents the years up evil the collapse of the g.d.r. the full of the wall and reunification a few of the paintings do express euphoria but more commonly loss and even pain. as well. as a kind of amputation not from the g.d.r. but from friends colleagues from your life the life in the west was totally different so we came from the warm nest of state support into the free market soon after the fall of the war i went to frankfurt and that was like jumping into very cold water indeed codice was all the exhibitions curator says that even today east
