When the Main Tower was completed in 1999, even the people of Frankfurt, who are spoilt by the city’s skyline, were impressed. A high-rise building with a façade made entirely of glass was built for the first time in Europe. In fact, the Main Tower consists of two high-rise buildings that are interlinked with one another. One is square, 170 metres high and the other is a round building 199.5 metres high with non-reflective glass. For the statics of the Main Tower, 112 bored piles (diameter 120 to 180 cm) are set 50 metres deep in the ground. The base section integrates the listed façade of the predecessor building, thus creating a link between the past and present.
This high-rise building is particularly popular with the people of Frankfurt and tourists. It is the only one in the city that has a publicly accessible viewing platform with restaurant. Furthermore, Europe’s highest radio and television studio is located on its 53rd/54th floor.
