Kollhoff Tower is also known as Potsdamer Platz 1. The tower is designed by architect Hans Kollhoff based on his vision of trans-Atlantic bridge building.
The Kollhoff Tower is now one of Berlins new city centre trademarks. The building rises in terraces into a tower which, with its 25 floors, represents one of the prominent features of the Berlin skyline.
There are green terraces on the roofs, and a panoramic café on the top floor offers a breathtaking view over Berlin city.
