The ceremonial raising of the United Nations flag in front of Haus Carstanjen on June 20, 1996, laid the foundation for Bonn's development into Germany's United Nations City. Today, the city of Bonn counts 25 UN institutions and representations with approximately 1,000 staff. The UN Campus around the former "Langer Eugen" high-rise building for members of parliament forms the heart of Bonn as an international location. For this year’s UN Talk on the occasion of 25 Years of UN City of Bonn, Mayor Katja Dörner and the moderators Insa Backe and Ralf Erdenberger will welcome contemporary witnesses and supporters who will speak about the beginnings and developments of the German UN City as well as about the perspectives of Bonn as an international location against the background of global challenges.
Former Mayor Bärbel Dieckmann, former Executive Director of the United Nations Environment Programme and former Federal Environment Minister Klaus Töpfer, and Richard Kinley, long-time Deputy Executive Secretary of the United Nations Climate Secretariat in Bonn, are expected to attend. The current head of the European Centre for Environment and Health of the World Health Organization (WHO), Francesca Racioppi, is also among the guests, as is the general music director of the Beethoven Orchestra Bonn, Dirk Kaftan. Also participating will be Bohyun Kim, former United Nations Volunteer, as well as Nancy Prieto and Neele Hartel from the student organization BIMUN/SINUB, who once a year simulate a United Nations conference with young delegates.
Currently, there are still free places for the face-to-face event at the Federal Art and Exhibition Hall. A ‘3G certificate’ is required for participation; masks are also compulsory (except when seated). Interested parties must register in advance by sending an e-mail to
