Bonn in the context of Bad Honnef

The Rhine-Ruhr metropolitan region (German: Metropolregion Rhein-Ruhr) is the largest metropolitan region in Germany, with over ten million inhabitants. A polycentric conurbation with several major urban concentrations, the region covers an area of 7,110 square kilometres (2,750 sq mi), entirely within the federal state of North Rhine-Westphalia. The Rhine-Ruhr metropolitan region spreads from the Ruhr area (Dortmund-Bochum-Essen-Duisburg) in the north to the urban areas of the cities of Mönchengladbach, Düsseldorf (the state capital), Wuppertal, Leverkusen, Cologne (the region's largest and Germany's fourth largest city), and Bonn in the south. The location of the Rhine-Ruhr at the heart of the European Blue Banana makes it well connected to other major European cities and metropolitan areas such as the Randstad, the Flemish Diamond and the Frankfurt Rhine Main Region.

The metropolitan area is named after the Rhine and Ruhr rivers, which are the region's defining geographical features and historically its economic backbone.

Geneva (/dʒɪˈniːvə/ jin-EE-və, Arpitan: [dzəˈnɛva] ; French: Genève [ʒ(ə)nɛv] ) is the second-most populous city in Switzerland and the most populous in French-speaking Romandy. Situated in the southwest of the country, where the Rhône exits Lake Geneva, it is the capital of the Republic and Canton of Geneva. Geneva is a global city, an international financial centre, and a worldwide centre for diplomacy, which has led to it being called the "Peace Capital".

It hosts the highest number of international organizations in the world, including the headquarters of many agencies of the United Nations and the ICRC and IFRC of the Red Cross. It was where the Geneva Conventions on humanitarian treatment in war were signed, and, in the aftermath of World War I, it hosted the League of Nations. It shares a unique distinction with municipalities such as New York City, Bonn, Basel, and Strasbourg as a city which serves as the headquarters of at least one critical international organization without being the capital of a country.

The Electorate of Cologne (German: Kurfürstentum Köln), sometimes referred to as Electoral Cologne (German: Kurköln), was an ecclesiastical principality of the Holy Roman Empire that existed from the 10th to the early 19th century. It consisted of the Hochstift—the temporal possessions—of the archbishop of Cologne, and was ruled by him in his capacity as prince-elector. There were only two other ecclesiastical prince-electors in the Empire: the Electorate of Mainz and the Electorate of Trier. The archbishop-elector of Cologne was also arch-chancellor of Italy (one of the three component titular kingdoms of the Holy Roman Empire, the other two being Germany and Burgundy) and, as such, ranked second among all ecclesiastical and secular princes of the Empire, after the archbishop-elector of Mainz, and before that of Trier.

The capital of the electorate was Cologne. Conflicts with the citizens of Cologne caused the elector to move to Bonn. The Free Imperial City of Cologne was recognized after 1475, thus removing it from even the nominal secular authority of the elector. Cologne and Bonn were occupied by France in 1794. The right bank territories of the electorate were secularized in 1803 during the German mediatization.

Cologne (/kə.ˈloʊn/ kə-LOHN; German: Köln [kœln] ; Kölsch: Kölle [ˈkœ̂lə] ) is the fourth-most populous city of Germany and the largest city of the German state of North Rhine-Westphalia with nearly 1.1 million inhabitants in the city proper and over 3.1 million people in the Cologne Bonn urban region. Cologne is also part of the Rhine-Ruhr metropolitan region, the second biggest metropolitan region by GDP in the European Union. Centered on the left bank of the Rhine, Cologne is located on the River Rhine (Lower Rhine), about 35 kilometres (22 mi) southeast of the North Rhine-Westphalia state capital Düsseldorf and 22 kilometres (14 mi) northwest of Bonn, the former capital of West Germany.

The city's medieval Cologne Cathedral (Kölner Dom) was the world's tallest building from 1880 to 1890 and is today the third-tallest church and tallest cathedral in the world. It was constructed to house the Shrine of the Three Kings and is a globally recognized landmark and one of the most visited sights and pilgrimage destinations in Europe. The cityscape is further shaped by the Twelve Romanesque churches of Cologne. Cologne is famous for Eau de Cologne, which has been produced in the city since 1709; "cologne" has since come to be a generic term.

Düsseldorf (German: [ˈdʏsl̩dɔʁf] ) is the capital city of North Rhine-Westphalia, the most populous state of Germany. It is the second-largest city in the state after Cologne and the sixth-largest city in Germany, with a 2024 population of 618,685. Most of Düsseldorf lies on the right bank of the Rhine, and the city has grown together with Neuss, Ratingen, Meerbusch, Erkrath and Monheim. Düsseldorf is the central city of Rhine-Ruhr, the second biggest metropolitan region by GDP in the European Union, that stretches from Bonn via Cologne and Düsseldorf to the Ruhr.

Düsseldorf began as a small settlement at the mouth of the Düssel River, gaining city rights in 1288 after the Battle of Worringen. In the Late Middle Ages and Renaissance, it grew into a regional political and cultural centre under the Dukes of Berg and later as the capital of the United Duchies of Jülich-Cleves-Berg. The 17th and 18th centuries saw flourishing arts and architecture, with Düsseldorf becoming known for its court culture and early art academy. During the Napoleonic era, it was briefly part of the Grand Duchy of Berg before coming under Prussian control in 1815, where it industrialised rapidly in the 19th century. During the 20th century, Düsseldorf developed into one of Germany’s most important centres for administration, business, and culture. In 1946, it became the capital of the newly created state of North Rhine-Westphalia, strengthening its political role.

West Germany was the common English name for the Federal Republic of Germany (FRG) from its formation on 23 May 1949 until its reunification with East Germany on 3 October 1990. It was sometimes known as the Bonn Republic after its capital city of Bonn, or as the Second German Republic. During the Cold War, the western portion of Germany and the associated territory of West Berlin were parts of the Western Bloc. West Germany was formed as a political entity during the Allied occupation of Germany after World War II, established from twelve states formed in the three Allied zones of occupation held by the United States, the United Kingdom, and France.

At the onset of the Cold War, Europe was divided between the Western and Eastern blocs. Germany was divided into the two countries. Initially, West Germany claimed an exclusive mandate for all of Germany, representing itself as the sole democratically reorganised continuation of the 1871–1945 German Reich.

The University of Bonn, officially the Rhenish Friedrich Wilhelm University of Bonn (German: Rheinische Friedrich-Wilhelms-Universität Bonn), is a public research university in Bonn, North Rhine-Westphalia, Germany. It was founded in its present form as the Rhein-Universität (English: Rhine University) on 18 October 1818 by Frederick William III, as the linear successor of the Kurkölnische Akademie Bonn (English: Academy of the Prince-elector of Cologne) which was founded in 1777. The University of Bonn offers many undergraduate and graduate programs in a range of subjects and has 544 professors. The University of Bonn is a member of the German U15 association of major research-intensive universities in Germany and has the title of "University of Excellence" under the German Universities Excellence Initiative.

Bonn has 6 Clusters of Excellence, the most of any German university; the Hausdorff Center for Mathematics, the Matter and Light for Quantum Computing cluster, Bonn Center for Dependency and Slavery Studies, PhenoRob: Research for the Future of Crop Production, the Immune Sensory System cluster, and ECONtribute: Markets and Public Policy. The University and State Library Bonn (ULB Bonn) is the central university and archive library of the Rheinische Friedrich-Wilhelms-Universität Bonn and North Rhine-Westphalia; it holds more than five million volumes.

The capital of Germany is the city of Berlin. It is the seat of the Federal President of Germany, whose official residence is Bellevue Castle. The Federal Council is the representation of the Lands of Germany and has its seat at the former Prussian House of Lords. Though most of the ministries are seated in Berlin, some of them, as well as some minor departments, are seated in Bonn, the former capital of West Germany. Although Berlin is officially the capital of Germany, 8,000 out of the 18,000 total officials employed at the federal bureaucracy still work in Bonn, about 600 km (370 mi) away from Berlin.

Ludwig van Beethoven (baptised 17 December 1770 – 26 March 1827) was a German composer and pianist. One of the most revered figures in the history of Western music, his works rank among the most performed of the classical music repertoire and span the transition from the Classical period to the Romantic era. Beethoven's early period, during which he forged his craft, is typically considered to have lasted until 1802. From 1802 to around 1812, his middle period showed an individual development from the styles of Joseph Haydn and Wolfgang Amadeus Mozart, and is sometimes characterised as heroic. During this time, Beethoven began to grow increasingly deaf. In his late period, from 1812 to 1827, he extended his innovations in musical form and expression.

Born in Bonn, Beethoven displayed his musical talent at a young age. He was initially taught intensively by his father, Johann van Beethoven, and later by Christian Gottlob Neefe. Under Neefe's tutelage in 1783, he published his first work, a set of keyboard variations. He found relief from a dysfunctional home life with the family of Helene von Breuning, whose children he loved, befriended, and taught piano. At age 21, he moved to Vienna, which subsequently became his base, and studied composition with Haydn. Beethoven then gained a reputation as a virtuoso pianist, and was soon patronised by Karl Alois, Prince Lichnowsky for compositions, which resulted in his three Opus 1 piano trios (the earliest works to which he accorded an opus number) in 1795.

The Rhein-Sieg-Kreis (Kölsch: Rhein-Siech-Kreis) is a Kreis (district) in the south of North Rhine-Westphalia, Germany. Neighboring districts are Rheinisch-Bergischer Kreis, Oberbergischer Kreis, Altenkirchen, Neuwied, Ahrweiler, Euskirchen, Rhein-Erft-Kreis, the urban district of Cologne. The federal city of Bonn is nearly completely surrounded by the district.

A pilgrimage church (German: Wallfahrtskirche) is a church to which pilgrimages are regularly made, or a church along a pilgrimage route, like the Way of St. James, that is visited by pilgrims.

Pilgrimage churches are often located by the graves of saints, or hold portraits to which miraculous properties are ascribed or saintly relics that are safeguarded by the church for their veneration. Such relics may include the bones, books or pieces of clothing of the saints, occasionally also fragments of the cross of Jesus, pieces of the crown of thorns, the nails with which he was fixed to the cross and other similar objects. Pilgrimage churches were also built at places where miracles took place.

The Basic Law for the Federal Republic of Germany (German: Grundgesetz für die Bundesrepublik Deutschland) is the constitution of the Federal Republic of Germany.

The West German Constitution was approved in Bonn on 8 May 1949 and came into effect on 23 May after having been approved by the occupying western Allies of World War II on 12 May. It was termed "Basic Law" (Grundgesetz, pronounced [ˈɡʁʊntɡəˌzɛts] ) to indicate that it was a provisional piece of legislation pending the reunification of Germany. However, when reunification took place in 1990, the Basic Law was retained as the definitive constitution of reunified Germany. Its original field of application (Geltungsbereich)—that is, the states that were initially included in the Federal Republic of Germany—consisted of the three Western Allies' zones of occupation, but at the insistence of the Western Allies, formally excluded West Berlin. In 1990, the Two Plus Four Agreement between the two parts of Germany and all four Allies stipulated the implementation of a number of amendments.

The capital resolution (German: Hauptstadtbeschluss) was made by the German Bundestag on 20 June 1991, as a result of German reunification, to move its headquarters, as well as the headquarters of half the federal ministries, from Bonn to Berlin. Ministries which remained in Bonn, such as the Federal Ministry of Defence, established secondary offices in Berlin; likewise the seats in Bonn turned to second offices for ministries which moved to Berlin.

The term capital resolution is misleading, since Berlin had already become the capital of the Federal Republic of Germany in 1990 as one of the stipulations of the Unification Treaty, and the resolution was to make it the seat of government as well.

The European Centre for Medium-Range Weather Forecasts (ECMWF) is an independent intergovernmental organisation supported by most of the nations of Europe. It is based at three sites: Shinfield Park, Reading, United Kingdom; Bologna, Italy; and Bonn, Germany. It operates one of the largest supercomputer complexes in Europe and the world's largest archive of numerical weather prediction data.

Colognian or Kölsch (pronounced [kœ̂lɧ], narrower [kœ̂ɫːʃ]; full name Kölsch Platt) is a small set of very closely related dialects, or variants, of the Ripuarian group of dialects of the Central German group. These dialects are spoken in the area covered by the Archdiocese and former Electorate of Cologne reaching from Neuss in the north to just south of Bonn, west to Düren and east to Olpe in northwest Germany.

The Cologne Bonn Region (German: Region Köln/Bonn) is a metropolitan area in North Rhine-Westphalia (NRW), Germany, covering the cities of Cologne, Bonn and Leverkusen, as well as the districts of Rheinisch-Bergischer Kreis, Oberbergischer Kreis, Rhein-Erft-Kreis and Rhein-Sieg-Kreis. The region covers an area of 3,839 km with 3.13 million inhabitants (population density 815/km). The city centres of Cologne and Bonn are 24 kilometres apart. At the outer city limits, there are only eight kilometres between Cologne-Libur and Bonn-Geislar.

The Cologne/Bonn Region was established by local governments within the Cologne Government Region in 1992, to promote common policies in regional and urban planning, traffic management, environment and investment. Among the most prominent co-operative projects are the Cologne/Bonn Airport, the Verkehrsverbund Rhein-Sieg and the former Bonn–Cologne Railway Company. Also the Stadtbahn of both cities are connected, so there are light rail trains from Cologne Stadtbahn in Bonn and the Bonn Stadtbahn in Cologne. The largest local banks, Sparkasse KölnBonn and Volksbank Köln Bonn, operate in both cities. Both cities are directly connected by the autobahn A555.

Lower Rhine (German: Niederrhein, pronounced [ˈniːdɐˌʁaɪn] ; kilometres 660 to 1,033 of the Rhine) is the section of the Rhine between Bonn in Germany and the North Sea at Hook of Holland in the Netherlands, including the Nederrijn (English: Nether Rhine) within the Rhine–Meuse–Scheldt delta; alternatively, Lower Rhine may also refer to just the part upstream of Pannerdens Kop (km 660–865.5), excluding the Nederrijn.

It is the last of the four sections of the Rhine between Lake Constance and the North Sea (the others being the High Rhine, Upper Rhine and Middle Rhine).

The Federal Ministry for Transport (German: Bundesministerium für Verkehr, German pronunciation: [ˈbʊndəsminɪsˌteːʁiʊm fyːɐ̯ fɐˈkeːɐ̯]; abbreviated BMV) is a cabinet-level ministry of the Federal Republic of Germany. Its main office is located in Berlin, while the majority of its civil servants and employees work in Bonn, the secondary seat.

The Ministry itself has about 1300 employees. At the top is the Federal Minister, and there are two Parliamentary Secretaries, who are also Member of the Bundestag, and two civil servant undersecretaries. The ministry oversees 63 downstream agencies and authorities where around 25,000 people work.
