This installation by Sir Tony Cragg is located at Remigiusplatz and was unveiled in 2014. Cragg is a British sculptor, but he has lived in Germany for long periods, having being knighted in 2016 for not just his artworks, but also for improving Anglo-German relations.
Apparently, the artwork is meant to highlight the “mediocrity of the economically orientated environment”, so its presence is a boost for the square in which it resides. It also has no correct angle for viewing, although I’d claim that the descriptive panel in front of the sculpture undermines that a little as, by necessity, it has created a front to the sculpture.
I have no in-depth knowledge of sculpture, or indeed any knowledge of sculpture, but it’s an interesting piece of artwork from which I can derive little meaning at all.
