SpaceWalk: A Spectacular Rollercoaster-Esque Staircase Loops Through a South Korean Park

Towering 70-meters above ground at its highest point, “SpaceWalk” is the latest undulating sculpture by Hamburg-based artists Heike Mutter and Ulrich Genth. The monumental staircase winds in loops and elevations similar to that of a rollercoaster throughout Hwanho Park in Pohang, South Korea, and is almost entirely accessible for pedestrians except for the innermost circuit. It’s the largest contemporary public sculpture ever installed in the country.
A follow-up to the pair’s 2011 project “Tiger & Turtle – Magic Mountain” in Duisburg, Germany, “SpaceWalk” is built of galvanized and stainless steels atop a cement foundation and embedded rows of LED lights. More
