Oberkassel - Mulheim (with train) - Oberkassel

Düsseldorf is located at the confluence of two rivers: the Rhine and the Düssel, a small tributary. The -dorf suffix means "village" in German (English cognate: thorp); its use is unusual for a settlement as large as Düsseldorf. Most of the city lies on the right bank of the Rhine. Düsseldorf lies in the centre of both the Rhine-Ruhr and the Rhineland Metropolitan Region. It neighbours the Cologne Bonn Region to the south and the Ruhr to the north. It is the largest city in the German Low Franconian dialect area (closely related to Dutch).

Mercer's 2012 Quality of Living survey ranked Düsseldorf the sixth most livable city in the world.[8][9] Düsseldorf Airport is Germany's fourth-busiest airport, serving as the most important international airport for the inhabitants of the densely populated Ruhr, Germany's largest urban area. Düsseldorf is an international business and financial centre, renowned for its fashion and trade fairs,[10][11][12] and is headquarters to one Fortune Global 500 and two DAX companies. Messe Düsseldorf organises nearly one fifth of premier trade shows.[13] As second largest city of the Rhineland, Düsseldorf holds Rhenish Carnival celebrations every year in February/March, the Düsseldorf carnival celebrations being the third most popular in Germany after those held in Cologne and Mainz.[14]

There are 22 institutions of higher education in the city including the Heinrich-Heine-Universität Düsseldorf, the university of applied sciences (Hochschule Düsseldorf), the academy of arts (Kunstakademie Düsseldorf, whose members include Joseph Beuys, Emanuel Leutze, August Macke, Gerhard Richter, Sigmar Polke, and Andreas Gursky), and the university of music (Robert-Schumann-Musikhochschule Düsseldorf). The city is also known for its influence on electronic/experimental music (Kraftwerk) and its Japanese community. Düsseldorf is classified as a GaWC Beta+ world city.
Mülheim received its town charter in 1808, and 100 years later the population exceeded 100,000, making Mülheim officially a city. At the time of the city's 200th anniversary with approximately 170,000 residents, it was counted among the smaller cities of Germany.
The northern foothills of the Rhenish Massif are characterised by the distinctive rock formation of the bare mountain slopes through which run coal-bearing layers which formed during the carboniferous period. Here the Ruhr cuts more than 50 meters deep into this Mittelgebirge. This natural erosion partly uncovered these mineable black coal deposits, which enabled their exploration and extraction using adits. However, the coal-rich layers became ever deeper as one progressed northward, which required setting up mines to extract the black coal. In contrast, the broad bayou (dead arm of a river) of Styrum borough is characteristic of the features of the Lower Rhine Plain.
