Tiger & Turtle - Magic Mountain is a large sculpture in the form of an accessible rollercoaster on a former slag heap, the Heinrich-Hildebrand-Höhe. Tiger & Turtle was created as the result of an international competition organised as part of the RUHR.2010 Capital of Culture. Today, the sculpture is one of the most photographed motifs of recent times. Those who climb the steps up to the loop are rewarded with a magnificent view.
