Katharina Grosse's Rainbow Explosion Invades Hamburger Bahnhof

German artist Katharina Grosse (b. 1961) has created a new monumental installation titled "It wasn't us" at the Hamburger Bahnhof – Museum für Gegenwart in Berlin, a former railway station turned museum. The work occupies both interior and exterior spaces, with Grosse stating, "I painted my way out of the building." The colorful sculptural presence resembles a natural rock or ice formation that appears to melt onto the floor, trailing a rainbow-like path outside. Museum director Gabriele Knapstein and curator Udo Kittelmann explain that the title refers to the intrinsic complexity and unpredictability of the conditions in which artists create and audiences perceive art. The location influenced the painting's development, as did the viewer's constantly shifting perspectives and unexpected interactions with the work.
