Julia Stoschek Collection

Cross over the Oberkasseler Bridge to the left side of the Rhine and check out the Julia Stoschek Collection, a lofty contemporary art space with a focus on video and multi-media and internet-based installations. Set in an early 20th-century former factory, the building itself is worth a visit, with a glass-walled rooftop and terrace offering incredible views of the river. Exhibitions change annually, and have included shows by such art-world luminaries as Trisha Donnelly and Turner Prize-winner Elizabeth Price. The collection is only open on Sundays. While you’re there, note the posh Oberkassel district, one of the wealthiest and most beautiful residential areas in the city. It was relatively spared from the WWII bombing that destroyed much of the rest of Düsseldorf, which means its gorgeous original Art Nouveau architecture is still intact, much of it concentrated around the Kaiser-Friedrich-Ring and Kaiser-Wilhelm-Ring.
