English: The photo shows the Ruhr University Bochum approaching the Ruhr area from the south in a gyrocopter (Sauerland) from an altitude of about 1900 feet (just under 600 m). In the foreground, the outflow of the Ölbach can be seen, which merges into Lake Kemnader, which itself has the Ruhr flowing through it. The Ruhr-Uni was built between 1964 and 1974 and is currently being renovated (until 2027). New at the time was above all the intended linking of natural sciences, engineering and the humanities. The university complex has been a listed building since 2015. The buildings themselves symbolise ships that have "docked" at their entrances, the roof of the Audimax (centre of picture) is reminiscent of a shell.
