The crown, like almost every other building on the skyline, is a bank. However, it is the only one with such a cantilevered construction. The individual beams are something 11 meters long and the construction is heated in winter to prevent the formation of icicles. The crown is intended to indicate that Frankfurt is the coronation city of the emperors of the Holy Roman Empire.
Now imagine that we are living in an energy crisis in the winter of 2022/2023. At that time, when the building was built, probably no one had the idea that such a thing can lead to problems. How does one get the idea to create such a building? Frankfurt bristles with such buildings, a true demonstration of money.
