The Sony Center is located in the historic heart of Berlin at Potsdamer Platz in the district of Berlin Mitte.
Designed by Helmut Jahn, the Sony Center is visually the most dramatic of the three Potsdamer Platz sections.
The heart of the Sony Center, is a central plaza dramatically canopied by a tentlike glass roof
with supporting beams emanating like spokes of a bicycle. (Source Lonely Planet).
