The Main Tower (official spelling: MAIN TOWER ) is a skyscraper in the city ​​center of Frankfurt am Main . It was inaugurated on January 28, 2000. With a height of 200 meters (with mast: 240 meters), it is together with Tower 185 the fourth tallest high-rise in Germany.

Planning and technology

The planning was carried out by the Hamburg architects Schweger + Partner. Parts of its lower floors are set in the historical facade of the original building.

The Main Tower was built from 1996 to 1999 by the "ARGE Main Tower" (including Hochtief AG and Philipp Holzmann AG).

With speeds of up to seven meters per second (25.2 km / h), the 26 passenger and three freight elevators are among the fastest in Germany.

In September 2011, the Main Tower was certified according to the standards of “ Leadership in Energy and Environmental Design (LEED)” with gold status.

In August 2016, the Main Tower was certified with platinum status according to the standards of “Leadership in Energy and Environmental Design (LEED)”.

The Main Tower has five basement floors and 56 upper floors as well as two publicly accessible viewing platforms (height: 198 meters and about 192 meters), which can be walked on for a fee, although the lower platform is only accessible to people with reduced mobility. There is also a public restaurant ( Main Tower Restaurant & Lounge ) with a cocktail lounge at a height of 187 meters, which was designed by Bernd Mey , on the 53rd floor .

The tenants in the Main Tower are Landesbank Hessen-Thüringen (Helaba), Merrill Lynch , NIBC Bank AG , the law firms Cleary, Gottlieb, Steen & Hamilton LLP and Sullivan & Cromwell LLP and, since 2006, the Australian Consulate and others. In the 53rd / 54th OG is Europe's highest fitness studio, PRIME TIME fitness. At the top there is a transmitting antenna for the radio programs hr-info and You FM .

Another user was the Hessischer Rundfunk , which operated a television studio here until October 2015. Since January 15, 2001, the weekly tabloid magazine maintower has been produced there, and the lottery numbers are drawn on Saturdays from April 2, 2005 to June 29, 2013 . Europe's highest fitness studio has been located here since July 2016.

Two works of art are accessible to the public in the foyer of the Main Tower: The video installation by Bill Viola The World of Appearances and the wall mosaic by Stephan Huber Frankfurter stairs / XX. Century .

After the attacks of September 11, 2001 , the publicly accessible viewing platforms were closed for several months for security reasons. The reopening only took place after a security gate had been installed in the foyer, as in airports, with the aim of preventing visitors from taking dangerous objects into the building.

Analog radio transmitter (VHF)

In the past, the 103.9 MHz was used with hr3 and the 90.4 MHz with hr4 (today You FM, also hr) and horizontally in operation at the radio station in Bertramstrasse with 1 kW each. The 97.6 MHz [0.3 kW D (90 ° –100 °, 130 ° –0 °) H] with Deutschlandfunk ran at Funkhaus Bertramstrasse until around October 2008. This has now been moved to the Europaturm . Today only the 87.9 MHz [0.1 kW ND H] with hr2 runs at the radio station Bertramstrasse.

Another transmitter from harmony.fm on 97.1 MHz [0.2 kW D (350 ° -160 °) H] is located in Ginnheim on a high-rise in Raimundstrasse. Due to the frequency, it can still be received better than the 105.4 MHz broadcast by the Europaturm . At the Raimundstrasse location there is also a transmitter from Klassik Radio on 107.5 MHz [0.2 kW D (10 ° –120 °, 160 ° –200 °, 260 ° –350 °) H].

The well-known first 4 programs of hr hr1 , hr2 , hr3 , hr4 and the private broadcaster Hit Radio FFH are broadcast from the tubular mast on the Großer Feldberg .
