What’s the best way to get a bird’s eye view of a city? You could ride a giant Ferris wheel! A new Ferris wheel called the Twin Eye is being planned for Seoul, South Korea, and it won’t just be massive—it will also have an unusual design.

The Twin Eye is set to be 591 feet (180 meters) high, about as tall as a 45-story building. It will have 64 enclosed capsules, each able to hold 20 to 25 people, which means it will be able to carry more than 1,400 passengers at once! Because of the wheel’s size, passengers will be treated to a panoramic view of Seoul once they reach the top. There will be fun at the bottom, too. The wheel will sit on top of a building where people can watch performances and buy food and drinks.

Many people are familiar with Ferris wheels. They’re commonly found at theme parks and carnivals. Most Ferris wheels have spokes, which are bars that connect the outer part of the wheel to the center of the wheel. The entire wheel rotates, moving each car to the top and then back down to the bottom. The spokes help provide support to the outer part of the wheel.

The Twin Eye will not have spokes, which suggests that riding it will be an unusual experience. Many times, with spokeless Ferris wheels, the wheel doesn’t move. Instead, the cars, or capsules, move around the edge of the wheel. The Twin Eye will look like a big, open circle in the sky.

The Twin Eye is set to be completed by the end of 2028.
