“Tiger and Turtle – Magic Mountain” by  German artists Heike Mutter and Ulrich Genth may look like a roller coaster from a distance, but it’s actually an elevated walkway and stairs.

The 21 meter high sculpture was built on a hilltop in Duisburg, Germany and towers over the surrounding lowlands.  It’s metal arcs and bends give the impression of speed. Visitors can climb onto the sculpture where it meets the ground, but a loop-the-loop at the center prevents anyone being able to walk a full circuit.
