The Siege of Bonn took place from 3 to 12 November 1673 in Bonn, Germany, during the Franco-Dutch War. Having forced the armies of Louis XIV to retreat, the Dutch in 1673 went on the offensive. At Bonn, a garrison consisting of troops from France and the Electorate of Cologne was besieged by a force from the Dutch Republic (commanded by stadtholder William III), the Holy Roman Empire (commanded by Raimondo Montecuccoli), and Spain. The allied forces captured the garrison following a nine-day siege. In 1689 Bonn was again the site of a major siege.

It is the oldest museum in Bonn and houses the antique collection of the University of Bonn with more than 500 antique statues and reliefs, and over 2,000 originals.

At this time collections of plaster casts were mainly used in the instruction of students at art academies. They were first used in the instruction of university students in 1763 by Christian Gottlob Heyne at University of Göttingen. The Akademisches Kunstmuseum in Bonn was the first of its kind, as at this time collections at other universities were scattered around universities libraries. The first director was Friedrich Gottlieb Welcker, who also held a professorship of archaeology. His tenure was from 1819 until his retirement in 1854. He was succeeded by Otto Jahn and Friedrich Wilhelm Ritschl, who shared the directorship. From 1870 to 1889 Reinhard Kekulé von Stradonitz, nephew of the famous organic chemist Friedrich August Kekulé von Stradonitz, was the director. In 1872 the museum moved to a new building that was formerly used by the department of anatomy. The building was constructed from 1823 to 1830 and designed by Karl Friedrich Schinkel and Hermann Friedrich Waesemann. Other directors of the museum were Georg Loeschcke (from 1889 to 1912), Franz Winter (from 1912 to 1929), Richard Delbrueck (from 1929 to 1940), Ernst Langlotz (from 1944 to 1966), Nikolaus Himmelmann (from 1969 to 1994) and Harald Mielsch (since 1994).

The federal city of Bonn (German pronunciation: [bɔn] (listen) Latin: Bonna) is a city on the banks of the Rhine in the German state of North Rhine-Westphalia, with a population of over 300,000. About 24 km (15 mi) south-southeast of Cologne, Bonn is in the southernmost part of the Rhine-Ruhr region, Germany's largest metropolitan area, with over 11 million inhabitants. It is a university city and the birthplace of Ludwig van Beethoven. It was the capital city of the Electorate of Cologne from 1597 to 1794 and of West Germany from 1949 to 1990. Founded in the 1st century BC as a Roman settlement in the province Germania Inferior, Bonn is one of Germany's oldest cities. From 1597 to 1794, Bonn was the capital of the Electorate of Cologne, and residence of the Archbishops and Prince-electors of Cologne. From 1949 to 1990, Bonn was the capital of West Germany, and Germany's present constitution, the Basic Law, was declared in the city in 1949. The era when Bonn served as the capital of West Germany is referred to by historians as the Bonn Republic. From 1990 to 1999, Bonn served as the seat of government – but no longer capital – of reunited Germany. Due to a political compromise (Berlin-Bonn Act) following the reunification, the German federal government maintains a substantial presence in Bonn. Roughly a third of all ministerial jobs are located in Bonn as of 2019, and the city is considered a second, unofficial, capital of the country. Bonn is the secondary seat of the President, the Chancellor, the Bundesrat and the primary seat of six federal government ministries and twenty federal authorities. The title of Federal City (German: Bundesstadt) reflects its important political status within Germany.The headquarters of Deutsche Post DHL and Deutsche Telekom, both DAX-listed corporations, are in Bonn. The city is home to the University of Bonn and a total of 20 United Nations institutions, the highest number in all of Germany. These institutions include the headquarters for Secretariat of the UN Framework Convention Climate Change (UNFCCC), the Secretariat of the UN Convention to Combat Desertification (UNCCD), and the UN Volunteers programme.

The Electoral Palace (German: Kurfürstliches Schloss) in Bonn is the former residential palace of the Prince-Electors of Cologne.

It was built by Enrico Zuccalli for the prince-elector Joseph Clemens of Bavaria from 1697 to 1705. The Hofgarten, a large park in front of the main building, is a popular place for students to meet, study and relax. The Hofgarten was repeatedly a place for political demonstrations, as for example the demonstration against the NATO Double-Track Decision on 22 October 1981, with about 250,000 participants.

Bonn Minster (German: Bonner Münster) is a Roman Catholic church in Bonn. It is one of Germany's oldest churches, having been built between the 11th and 13th centuries. At one point the church served as the de facto cathedral for the Archbishopric of Cologne, because it is the major church of what was then the Archbishop-Elector's residence (Cologne itself having secured independence from his secular government). It is now a minor basilica. It served as the inspiration for the Kaiser Wilhelm Memorial Church in Berlin, as Kaiser Wilhelm II had studied in Bonn.
