In the 7th and 8th centuries, the odd farming or fishing settlement could be found at the point where the small river Düssel flows into the Rhine. It was from such settlements that the city of Düsseldorf grew.
The first written mention of the town of Düsseldorf dates back to 1135 (then called Dusseldorp). It was told that under Emperor Friedrich Barbarossa the small town of Kaiserswerth, lying to the North of Düsseldorf, became a well fortified outpost, where soldiers kept their watchful eyes over every movement on the Rhine. Kaiserswerth eventually became a suburb of Düsseldorf in 1929.
