A few days ago a big Urban Art Festival organized by STREETARTARCHIVE.NET and SONICONER went down at the Berlin Teufelsberg-Grunewald area. It is a man-made hill in Berlin, Germany, in the Grunewald locality of former West Berlin and the hill is made of rubble, and covers an under-construction Nazi military-technical college. During the Cold War, there was a U.S. listening station on the hill, Field Station Berlin, which is abandoned now and painted over and over again. This time by street artists and graffiti writers like Bustart, Boosher, El Bocho, HNRX, Fabifa, Kobe, Marshal Arts and many more! Take a look onsome selected works elow, the event was supported by MOLOTOW.More photos will follow up on the website streetart.limited!
