The Rheinturm was inaugurated on 1 December 1981.[2] 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 to 23:30.
As a special attraction, a light sculpture on its shaft 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[citation needed]. The clock is a 24-hour clock with six sets of lights, two each for the Hour (00 to 24), Minutes (00 to 60), and Seconds (00 to 60), to be read from top to bottom.
