Rhine Tower

With its height of 234 metres, the Rhine Tower (Rheinturm) is the first construction built completely of reinforced concrete. The tower is home of the world's largest decimal clock, visible on the concrete shaft. The watch was developed by the light artist Horst H. Baumann and received an entry in the Guinness Book of Records. The exclusive restaurant 'Top 180' rotates around the shaft of the tower once an hour. At a height of 168m there is a cafeteria and below it at 164m an open observation deck. These facilities for the general public were inaugurated in March 1982. In 1984, the Rhine Tower was awarded a prize as an exemplary building by the North Rhine-Westphalian minister for urban development, housing and transport (text from www.duesseldorf.de).
