The Sony Center and Potsdamer Platz, a hub of urban design in Berlin, Germany is a profile of modern architecture and metropolitan infrastructure. With a blend of concrete, glass, metal, and other composite materials, the city skyline is illuminated with tints and shades of white, black, and grey. High above the zebra crossing and subway station, the pedestrian bridge provides a handrail for a view of the patterned asphalt, tile, and flooring below.
