Düsseldorf is an international business and financial centre and renowned for its fashion and trade fairs. Located within the Blue Banana, the city is headquarters to five Fortune Global 500 and several DAX companies. Messe Düsseldorf claims to organize nearly one fifth of all world‘s premier trade shows.
Culturally, Düsseldorf is known for its academy of fine arts (Kunstakademie Düsseldorf, e.g. Joseph Beuys, Emanuel Leutze, August Macke, Gerhard Richter, Sigmar Polke and Andreas Gursky), its pioneering influence on electronic/experimental music (Kraftwerk) and its relatively large Japanese community. As a city by the river Rhine, Düsseldorf is a stronghold for Rhenish Carnival celebrations. Every year in July more than 4.5 million people visit the city's Largest Fair on the Rhine funfair.
The Rheinturm (pronounced [ˈʁaɪ̯ntʊʁm]) (Rhine Tower) is a 240.5 metre high concrete telecommunications tower in Düsseldorf, capital of the federal state (Bundesland) of North Rhine-Westphalia, Germany. Construction commenced in 1979 and finished in 1981. The Rheinturm carries aerials for directional radio, FM and TV transmitters. It stands 174.5 metres high and houses a revolving restaurant and an observation deck at a height of 170 metres. It is the tallest building in Düsseldorf.
The Rheinturm was inaugurated on 1 December 1981. It contains 7,500 cubic metres of concrete and weighs 22,500 tons. Before October 15, 2004, when an aerial antenna for DVB-T was mounted, it was 234.2 metres high.
The observation deck is open to public, daily from 10:00 AM to 11:30 PM. As a special attraction, there is a light sculpture on its shaft which works as a clock. This sculpture was designed by Horst H. Baumann and is called Lichtzeitpegel (light time level). The light sculpture on the Rheinturm is the largest digital clock in the world.
