Author from Ilmenau, who wrote a book about Jonastal and believes the Amber Room could be hidden in blasted parts of the tunnel system Olga SIII. He follows eye witnesses saying that trucks with carpets and tiles would have arrived and that a part of the underground system would have been ready. According to the investigations of our organisation, we do not believe that such a completed system exists. There is no further evidence and the condition of the tunnels today lead to the conclusion that the project was far from being ready. Still a very good book!
