Etymology

The name Aachen means "water" or "stream". It started with the Latin name Aquae, because of the warm mineral springs there. People have lived in Aachen for about 5,000 years.

After Charlemagne built his palatine chapel, the city became known as Aix-la-Chapelle to distinguish it from another place called Aix-en-Provence. Today, Aachen has many names in different languages.

Early history

Flint quarries on the Lousberg, Schneeberg, and Königshügel, first used during Neolithic times (3000–2500 BC), show that people lived in Aachen a long time ago. During the Iron Age, Celtic people lived in the area. They were drawn to the marshy basin’s hot sulphur springs, where they worshipped Grannus, a god of light and healing.

The Romans built a spa town called Aquae Granni around 124 AD. They added baths, water pipelines, and a temple. Later, the town was taken over by the Ripuarian Franks.

Middle Ages

In the Middle Ages, Aachen became very important. Charlemagne chose it as his main home and built a grand palace and church there. Many kings and emperors were crowned in Aachen. The city also had a Jewish community and was a center for making important books.

16th–18th centuries

In the 16th century, Aachen began to lose its power. Wars and fires damaged the city. It became known for its hot springs and spas. Important treaties were signed there, shaping the history of Europe.

19th century

When France took over Aachen, it was later given to Prussia. The city grew with new railways and factories. But living conditions were very bad until new housing was built.

20th century

World War I, Interwar Period, World War II

Aachen was involved in both World Wars. During World War II, it was heavily bombed and later became the first German city captured by Allied forces.

Geography

Aachen is located in the middle of the Meuse–Rhine Euroregion, near where Germany, the Netherlands, and Belgium meet. Nearby towns include Vaals in the Netherlands, just 6 kilometers away, and Heerlen and Eupen, about 20 kilometers away. The city is near the valley of the Wurm river and close to the High Fens and the Eifel hills.

Aachen has a temperate climate with mild winters and warm summers. It gets more rain than some other German cities because of its location and the nearby hills. The city's weather is also influenced by warm winds called Foehn winds. Even though it is in Germany, Aachen's winters are milder than in places farther east because it is closer to the sea.

Geology

The geology of Aachen is very varied. The oldest rocks around the city come from the Devonian period. They include sandstone, greywacke, claystone, and limestone. These rocks are part of the Rhenish Massif.

Later, during the Cretaceous period, the ocean reached this area. It left behind clay, sand, and chalk. These materials formed the hills of the Aachen Forest and the Lousberg.

Aachen has many thermal springs along old fault lines. The area has also had earthquakes, like the one in 1992.
