On June 17, 1991, the governments of Poland and Germany signed the Treaty on Good Neighborliness and Friendly Cooperation. A historic new beginning. The partnership between the cities of Düsseldorf and Warsaw has existed even longer - this year it celebrates its 35th anniversary! To mark this celebration, we are joining the Office for International & European Affairs, experts and our audience to discuss what it takes for understanding to succeed. What can we learn from one of the most successful reconciliation processes since the Second World War - in the face of social division and international conflicts? A dinner with impulses, a three-course menu and artistic intermezzi. - In cooperation with the Office for International & European Affairs of the City of Düsseldorf and "Warsaw Week"
