The Rheinturm (built 1979 – 1982, architect H. Deilmann) is a striking landmark on the Düsseldorf’s Rhine skyline. It stands on the edge of the southern city centre, at the entrance to the MedienHafen, right beside the North Rhine-Westphalian parliament building (Landtag) and the building of the public broadcaster, Westdeutscher Rundfunk. It is 240.5 metres high, with a glass-fronted 180-seat restaurant at an altitude of 172.5 metres that rotates on its axis. A bar and lounge is located below the restaurant (168m) as is a viewing platform (164m) with a breathtaking view of the Rhine metropolis: the MedienHafen, the Altstadt, the Hofgarten, Königsallee and the Rhine with its family of bridges all lie at the feet of the tower. When the weather is good, one can see as far as Cologne Cathedral. Thanks to a level entrance in the basement of the tower, the building offers barrier-free access.
