Tiger and Turtle – Magic Mountain in Duisburg, Germany

From afar, visitors see a roller coaster standing alone on a green hill.

When approaching, they find out that it is not a roller coaster running at high speeds, but an accessible structure with a staircase of a total of 705.3 ft.

After two years of planning and completion, the large outdoor sculpture called "Tiger and Turtle - Magic Mountain" opened to the public in November 2011.

From that time on, the coaster has been enthroned on Heinrich Hildebrand Height, an artificial hill 98.4 ft high, heaped up with zinc slag in the South of the German town of Duisburg, where it is visible from a considerable distance. At a height of 147.6 ft above ground, visitors can enjoy the breathtaking view over the landscape of the Western Ruhr.

The plan of the "roller coaster for pedestrians" was created by two artists from Hamburg, Heike Mutter and Ulrich Genth.

Building

The supporting structure consists of spatially precambered main beam pipes lying on 17 built‑in steel columns.

Cross beams cantilevering on both sides are fixed to the pipe where a walkable grating with a width of 3.2 ft is applied. The span lengths of the main beam pipe vary from 22.9 to 49.2 ft.

The irregular column arrangement is based on the results of research by structural engineers from Berlin, optimizing the structure's behavior concerning deformation and vibration. Horizontal vibration dampers were installed in significant span areas.
