Want to walk up a giant, looping roller coaster?

On November 13, 2011, the “Tiger & Turtle – Magic Mountain” sculpture in Duisburg, Germany, opened to the public. This isn’t your average piece of public art, however, as it is designed like a giant roller coaster with stairs and slopes that people can actually walk on.

Traversing over the sculpture, visitors will be put 148 feet above the surrounding countryside, gaining access to great views of the famous Rhine. While trekkers will reach great heights, they unfortunately will not get to go upside down, as the intimidating-looking loop actually contains stairs that keep you standing straight up.

The piece, which took one year to build, was created by German artists Heike Mutter and Ulrich Genth, who describe the sculpture like this:

“The curved flight of stairs inscribes like a signature on the landscape and recruits the nimbus of the classical roller coaster. Having a closer look, the public is disappointed in a disarming way. The visitor climbs on foot via differently steep steps the roller-coaster-sculpture. So the sculpture subtly and ironically plays with the dialectic of promise and disappointment, mobility and standstill. Visitors happen to briefly meet with oncoming visitors on the steep and about 1m | 1yd wide corridors. Led-lights are integrated in the handrails and highlight the flight of stairs so the sculpture is accessible at night, too.”

Make sure to visit during the day, as well as at night, when the LED lights are on.
