The name Magdeburg is above all inextricably linked with a technical discovery: The Magdeburg hemispheres were used by Otto von Guericke, born in Magdeburg in 1602, to prove the existence of the surrounding air pressure he discovered. The power of 16 horses was not sufficient to separate the metal hemispheres, which were connected in a vacuum. Otto von Guericke is considered a pioneer in experimental physics, but he also invented air pumps and barometers. As mayor of the city of Magdeburg, he took part in the negotiations on the Peace of Westphalia, which ended the 30-year war. Today the university bears the name Otto von Guerickes and is a central component of a distinctive scientific landscape in the region.
Magdeburg's striking landmark is the cathedral, the first Gothic building in Germany. Built in 1209, the cathedral dates back to a Romanesque predecessor that Emperor Otto I had built in 937. The cathedral also contains the tomb of the first emperor and founder of the Holy Roman Empire. Among the impressive medieval buildings are the Romanesque monastery "Unser Lieben Frauen" and the town hall with the famous "Magdeburger Reiter", the first freestanding equestrian monument in Northern Europe.
Magdeburg, which was largely destroyed in the last days of the Second World War, developed into a modern and lively city. New landmarks such as the Grüne Zitadelle, the last and largest single building of the Austrian artist Friedensreich Hundertwasser, were added, old ones were rediscovered and restored or rebuilt, such as the Festung Mark or the Bastion Kleve, which bear witness to Magdeburg as a mighty fortified city.
