Gottfried Helnwein’s photography project “Ninth November Night," a spectacular work of art that recalls the destruction of the synagogues during the so-called “Reichskristallnacht,” was itself the target of an attack. On Monday night an unknown person destroyed all seventeen child portraits with knife slashes. The portraits had been set up between the Museum Ludwig and the Dome of Cologne. Helnwein had financed the project himself.
