Heinrich Hertz Tower

The Heinrich Hertz Tower is a landmark radio telecommunication tower in the city of Hamburg, Germany.Designed by architect Fritz Trautwein, in co-operation with civil engineers Jörg Schlaich, Rudolf Bergermann and Fritz Leonhardt, the tower was built between 1965 - 1968 for the former Deutsche Bundespost near '''' park.With an overall height of 279.2 m it is Hamburg's tallest structure, consisting of a 204 m steel-reinforced concrete lower section topped by a 45 m steel-lattice tower and a three-segmented cylinder of about 30 m, which supports various antennas. There are eight concentric platforms stacked one above the other: starting at 128 m with the two-story observation and restaurant platform, served by two high-speed elevators. Above that at 150 m is the operations platform housing the workforce and equipment, and further up six differentially sized, smaller open platforms in same distances, populated with high-gain directional microwave radio relay antennas . Number nine was added at 25 m height in July 2005. After the observation platform and restaurant were closed due to asbestos decontamination, former stuntman Jochen Schweizer had a bungee jumping base installed. The restaurant will not open again due to new fire escape regulations, and the bungee platform was closed at the end of 2001.
