A closer look at the chronicle - by the way, presented as a timeline on the UN Bonn website ( ), shows the highlights of the past 25 years. You can see the settlement of organizations large and small, starting with the United Nations Climate Secretariat and the Convention to Combat Desertification and continuing to UN Habitat's Global Water Operators' Partnerships Alliance, which only settled in Bonn in 2020.
25 years of UN City - 25 UN organizations in Bonn
As the 25th organization in the 25th anniversary year of UN Bonn, an office of the United Nations Development Programme (UNDP) has recently moved to the UN Campus on the Rhine, with a branch office in Berlin. The new UNDP office aims to strengthen development policy cooperation with the German government.
The development of the UN Campus itself has seen further milestones - the handover of Langer Eugen as the main building in summer 2006 by German Chancellor Angela Merkel to UN Secretary-General Kofi Annan, the handover of the renovated former parliamentary building in 2013, and soon the occupation of a new building. To mark the anniversary, the city has commissioned the production of a short film on the UN Campus, providing a glimpse behind the fence that surrounds the site for security reasons.

The opening of the World Conference Center Bonn in 2015 is another milestone in Bonn's UN history, as it provides the United Nations with a meeting facility for major conferences. The WorldCCBonn demonstrated its capabilities in 2017 - with the World Climate Conference, which drew more than 22,000 people to Bonn.
Mayor Dörner: United Nations belong to Bonn
On the anniversary, Mayor Katja Dörner pays tribute to the work of the United Nations in Bonn: "In a way, 20 June 1996 was the birth of Bonn as a UN City and thus a very special day for our city. Since then, the United Nations has been a natural part of Bonn, underlining the internationality and cosmopolitanism that have characterized this city for decades. All of the 25 organizations now based here on the banks of the Rhine are concerned with sustainability, the future topic par excellence."
However, Bonn is not only the German host city for the UN, as Mayor Dörner points out: "As a city, we also see ourselves as having a responsibility, especially when it comes to such significant issues as environmental and climate protection, the Sustainable Development Goals and peace and justice in our world. Therefore, it is an important concern for us to support the work of the United Nations in Bonn and to make it visible."
Executive Director of the United Nations Volunteers Programme, Toily Kurbanov emphasizes: "The United Nations Volunteers Programme has a special relationship with Bonn: UNV was the first organisation to move its headquarters to the German UN city and has spent 25 years of its 50th anniversary here. From Langer Eugen, we work with our teams around the world to send volunteers to the United Nations. In 2020 alone, almost 10,000 UN volunteers supported the work of our partners in 150 countries. Our thanks go to the Government of the Federal Republic of Germany and the City of Bonn, who together make our colleagues from all over the world feel at home.”
On June 20, Bonn celebrates the special anniversary - unfortunately not with a big party, as originally planned, but "only" virtually. Nevertheless, there are congratulations - in the form of video messages featured on the German and English anniversary websites at and .
Congratulations have been extended by UN Secretary General Antonio Guterres and the Minister President of North Rhine-Westphalia, Armin Laschet, amongst others.

Tram promotes UN anniversary
A “UN tram” will soon be attracting attention in the cityscape, operating on light rail line 66 between Siegburg and Bad Honnef. It was designed by the Bonn artist "Özi", who is known to many as the creator of the two climate license heroes BONNi and BO. Anyone who sees the tram is invited to take a photo and post it on social media by using the hashtag #UNBonn25.
Already since mid-May, the city has been promoting the anniversary with banners and flags along the B9. Throughout June, info screens at Bonn's main train station and at the Moltkestraße tram stop in Bad Godesberg will also point to the anniversary. A mobile textile wall and an illuminated column in the foyer of the City Hall as well as other illuminated columns in the Service Center and in the district town halls will also attract attention in this regard.
