Nestled among the shops on Adalbertstraße stands the Kugelbrunnen, a dynamic stainless-steel sculpture. Created in 1977 by Albert Sous, the work incorporates, among other things, the drums of old washing machines. Three nested spheres rest on a simple pipe that marks the height of the fountain. If you pause for a moment, you’ll see the unique effect of the material as it interacts with light and water. The fountain’s kinetic quality makes the square feel more open and seamlessly blends technology with city life.
