UNStudio designs world’s highest-standing spokeless Ferris wheel in Seoul

Dubbed the Seoul Twin Eye, the 590-foot-tall spokeless Ferris wheel will be formed of two intersecting rings, with each ring carrying pods that revolve around inside and outside tracks. The structure will accommodate 64 capsules, each carrying 20–25 people, allowing for an overall capacity of more than 1,400 people simultaneously, almost double the capacity of the London Eye.

The scheme’s form was inspired by the concept of an Honcheonsigye, an astronomical clock that represents the movement of celestial objects through time. In addition to providing a visual representation of “unity,” the double ring form also provides enhanced structural stability for earthquakes and high winds, according to the team.

“Located in the heart of the city, this spokeless design references Korea’s boundless ambition for innovation and spirit of progress, seamlessly blending cutting-edge technology with a timeless appreciation for stability and beauty,” said UNStudio founder Ben van Berkel about the design.

The wheel will sit atop a 130-foot-tall cultural complex that will house an exhibition space, a performance hall, retail, and food & beverage outlets. The proposal also includes plans for a monorail connecting the Ferris wheel to a nearby subway station, as well as a zip line.

Construction on the scheme is expected to begin construction in 2025, with completion planned for 2028.
