The “One Wall, One Mural” project is led by the non-profit organization Urban Nation. They have brought well-known street artists to the Reineckendorf district in Berlin to paint large murals on the sides of apartment buildings. When I was there in August 2018, there were 6 murals.

These pictures were taken in August 2018. Since then, another large mural has been painted on one of the remaining buildings. It was a collaboration between Nuno Viegas, and the German pair, Hera and Akut. I don’t have a picture of it but this link will take you to Urban Nation’s description of the mural.
