Bonn is a special city in Germany, located in the state of North Rhine-Westphalia. It sits right on the Rhine River. More than 300,000 people live here! Bonn is about 24 kilometers (15 miles) south of Cologne. It's part of the Rhine-Ruhr region, which is Germany's largest metropolitan area. This big area has over 11 million people.

Bonn has a very important history. It was the capital of West Germany from 1949 until Germany became one country again in 1990. After that, it was the capital of reunited Germany until 1999, when the government moved back to Berlin. Bonn is also where Germany's current constitution, called the Basic Law, was created.

The city was founded way back in the 1st century BC by the Romans. This makes Bonn one of Germany's oldest cities. For a long time, from 1597 to 1794, it was the capital of the Electorate of Cologne. Even though Berlin is now the main capital, Bonn still has a big role in the German government. Many government jobs are still in Bonn, and it's sometimes called a "second capital." Bonn is known as a "Federal City" (Bundesstadt) because of its important political status.

Bonn is also home to big companies like Deutsche Post DHL and Deutsche Telekom. The famous University of Bonn is here, along with 20 United Nations offices. These include important groups working on climate change and fighting desertification. Plus, Bonn is the birthplace of the famous composer Ludwig van Beethoven. It's also a fun place for the Rhenish Carnival and a popular spot for tourists because of its beautiful location on the Middle Rhine.

Where is Bonn?

Bonn is in the southern part of the Rhine-Ruhr region, which is Germany's biggest metropolitan area. It's located in the German state of North Rhine-Westphalia, right next to the state of Rhineland-Palatinate. The city covers more than 141 square kilometers (54 square miles) on both sides of the Rhine River. Most of the city is on the left side of the river.

To the south and west, Bonn is close to the Eifel region, which has the Rhineland Nature Park. To the north, it borders the Cologne Lowland. Natural boundaries include the Sieg River to the northeast and the Siebengebirge (Seven Hills) to the east. The city is about 15 kilometers (9 miles) long from north to south and 12.5 kilometers (8 miles) wide from west to east.

How Bonn is Organized

The state of North Rhine-Westphalia is split into five governmental districts. Bonn is part of the governmental district of Cologne. Within this district, Bonn is its own special "urban district." This urban district is then divided into four main parts: Bonn, Bonn-Bad Godesberg, Bonn-Beuel, and Bonn-Hardtberg. In 1969, some nearby towns like Bad Godesberg and Beuel joined Bonn, making the city much larger than it was before.

Bonn's Weather

Bonn has an oceanic climate, which means it has mild temperatures. It's in the Rhine valley, making it one of Germany's warmer areas.

History

Bonn's Roman Beginnings

2008-12-25 Bonn Sterntor
The Sterntor (Star Gate) was rebuilt using parts of the old medieval city wall. It was first built around 1244.

Bonn's history goes back to the time of the Roman Empire. Around 12 BC, the Roman army set up a small camp here. Even before that, the Romans had settled a Germanic tribe called the Ubii in the area. The Latin name "Bonna" might come from the original people who lived here, the Eburones.

Later, in the 1st century AD, the Romans built a huge military fort called Castra Bonnensis (Fort Bonn). This fort was made of wood at first, then rebuilt with stone. It was used by the Roman army until the mid-5th century. The fort was so big it could hold a full Roman legion (a large army unit) and its helpers. It covered about 250,000 square meters (62 acres)! Inside, it had many streets and buildings, like headquarters, officers' quarters, and barracks.

A main Roman road connecting important cities like Cologne and Mainz went right through the fort. A local town, also called Bonna, grew up along this road. Later, much of the Roman town was destroyed by invaders. The people who remained moved inside the fort for safety. From this fort, and a new settlement around what became the Bonn Minster, the medieval city of Bonn grew. The Sterntor (star gate) in the city center today is a reconstruction using parts of the old medieval city wall.

From Middle Ages to Modern Times

University bonn at night
The University of Bonn, founded in 1818, has had famous students like Nietzsche and Marx.

Between the 11th and 13th centuries, the beautiful Romanesque style Bonn Minster church was built. In 1597, Bonn became the main city for the Archdiocese of Cologne. This made the city more important and it grew a lot.

In 1794, French troops took over Bonn, and it became part of the First French Empire. After the Napoleonic Wars in 1815, Bonn became part of the Kingdom of Prussia. It wasn't a very important city during these years.

Bonn as Germany's Capital (The "Bonn Republic")

After World War II, Bonn was in the British zone of Germany. In 1949, when West Germany was formed, Bonn became its capital. It was called the "temporary seat of the Federal institutions." Even though Berlin was officially the capital of Germany, Bonn was chosen as the temporary capital. This was because leaders like Konrad Adenauer wanted Berlin to be the capital of a reunited Germany someday. They felt that choosing a big city like Frankfurt as a permanent capital might make people forget about reuniting Germany.

In 1949, the German constitution, the Basic Law for the Federal Republic of Germany, was written and approved in Bonn. Bonn was the political center of West Germany for many years. This time is often called the Bonn Republic.

After Germany Reunited

Hammerschmidt Villa was the main home for the President of Germany from 1950 to 1994. Now it's the President's second home.

When Germany reunited in 1990, Berlin became the official capital again. But there was a big discussion about whether the government offices should move to Berlin or stay in Bonn. Some people wanted the government to move to Berlin because it was the historic capital. Others wanted it to stay in Bonn because it was closer to important European organizations.

Finally, in 1991, the German parliament voted to move the main government offices to Berlin. The vote was very close! Even so, Bonn still has a special role. It's called the "Federal City" (Bundesstadt). The President and Chancellor still have offices in Bonn. Many government ministries, like the Ministry of Food & Agriculture and the Ministry of Defence, also have large offices here. More than 8,000 federal officials still work in Bonn. Also, 19 United Nations (UN) organizations have offices in Bonn today.

Culture

Bonn has many interesting places to visit! Beethoven's birthplace is located near the market square. Next to the market is the Old City Hall, built in 1737 in the beautiful Rococo style. It's used for special events and as the mayor's office.

It connects the Kurfürstliches Schloss with the Poppelsdorfer Schloss, another palace that is now a botanical garden.

The Beethoven Monument stands in Münsterplatz, a square next to the Bonn Minster. This church is one of Germany's oldest. The tallest buildings in Bonn include the Post Tower (162.5 meters or 533 feet tall), which is the headquarters of Deutsche Post, and the Langer Eugen (114.7 meters or 376 feet tall), which is now the United Nations Campus.
