The second section of the tunnel on Bismarckstraße was completed in 2022. The mural focuses on the Arctic Circle and depicts an icy landscape at sunset. At first glance, everything seems fine here — an orca leaps out of sheer joy, and penguins play — but a little further away, a polar bear stands on a drifting ice floe with its youngsters. A bald eagle spreads its wings in warning. The neighboring castle is not so harmless; with its surveillance cameras and greenish-smoking chimneys, it seems more like a prison. Did the fat raccoon just barely escape?
