Walking through Berlin’s commercial southern neighborhood of Steglitz, one wouldn’t expect to be confronted with the urban art that the city has become known for.

Four international artists—Honet, Flying Förtress, Soyzone and Craig KR Costello—decided to seize the opportunity on this banal city street for an unconventional visual intervention by painting the 48 meter high observation tower rising up above the street. Previously brick red, the tower—known as the Bierpinsel—was built in 1976 and contains a cafe with a 360-degree view of the surrounding city.

Located directly above the Schloßstraße U-Bahn station this bulbous structure was subsequently renamed Turmkunst and required 2000 liters of paint to finish the project. The outcome is an abstract and slightly personified spectacle that employs bold controlled patches of colors and free forming drips.

The sheer size of the building makes for a striking visual presence, however, the real surprise is located underground in the U-Bahn station where intricate and vibrant graffiti-like paintings consume most of the wall space.
