The Iconic Capital Landmark: 15 Fascinating Facts About the London Eye

1. It Isn't Technically a Ferris Wheel

Despite being routinely described as a giant Ferris wheel, engineers categorize the London Eye as a cantilevered observation wheel. Unlike traditional Ferris wheels, which feature passenger cars dangling underneath a dual-supported frame, the Eye's sealed capsules sit on the outer rim. Furthermore, the entire structure is supported by a massive A-frame anchor on only one side of the River Thames. Electric motors turn the heavy wheel rim within a rigid ring of high-tech cable stabilization, keeping the capsules level as they orbit. This radical design makes it the tallest cantilevered observation wheel in the world.

2. The Number 13 Was Skipped Out of Superstition

The London Eye features 32 enclosed passenger capsules, with each single car representing one of the 32 official boroughs of Greater London. However, if you step into the final capsule on the wheel, you will notice that it is clearly labeled with the number 33. The architects intentionally skipped capsule number 13 to avoid inviting bad luck upon the landmark, giving in to triskaidekaphobia. Because of this intentional counting anomaly, there is no car 13 anywhere on the attraction. Riders stepping onto capsule 33 are actually boarding the 32nd car on the wheel.

3. It Revolves So Slowly That Passengers Board While It Moves

The London Eye turns at a steady, relaxing pace of just 26 centimeters per second, which equals roughly 0.6 miles per hour. Because the wheel moves at approximately twice the speed of a crawling tortoise, it does not actually stop to let passengers board or exit. Instead, visitors simply step on and off the moving capsules while the structure maintains continuous rotation. The operator only brings the wheel to a complete halt to allow elderly or disabled passengers to board safely. A single full rotation takes approximately 30 minutes, giving guests plenty of time to enjoy panoramic views.

4. On a Clear Day, You Can See All the Way to Windsor Castle

Rising to a total height of 135 meters (443 feet), the London Eye offers unrivaled vantage points over the British capital. On a clear day, visibility from the top of the wheel stretches for roughly 25 miles (40 kilometers) in every direction. Sharp-eyed visitors looking toward the western horizon can spot the iconic outline of Windsor Castle, an official residence of the monarch. The high elevation also provides stunning views of famous capital landmarks like Big Ben, St. Paul's Cathedral, and the Shard. It remains one of the best viewing platforms in the entire United Kingdom.

5. Richard Branson Mocked Construction Delays with a Cheeky Blimp Prank

During the wheel's construction in late 1999, the engineering team faced an embarrassing setback when an attempt to hoist the structure upright failed due to technical issues. The primary sponsor of the project at the time was British Airways, the fierce rival of Sir Richard Branson's airline, Virgin Atlantic. Spotting a golden opportunity for a public prank, Branson immediately dispatched a Virgin-branded airship to fly over the Thames site. The blimp displayed a massive banner reading "BA Can't Get It Up" to the delight of gathered onlookers. The hilarious stunt made front-page news across Britain and cemented the corporate rivalry in marketing history.

6. It Was Originally Intended to Be Removed After Five Years

When the London Eye was conceived as a landmark to celebrate the turn of the millennium, town planners never intended it to be permanent. Officials originally granted temporary planning permission for the structure to stand on the South Bank for just five years. However, its immense popularity among tourists and locals quickly turned it into a cherished symbol of modern London. Recognizing its enormous cultural and economic value, Lambeth Council granted a permanent operating license in 2002. Much like the Eiffel Tower in Paris, what began as a temporary exhibition piece became a permanent defining icon of the cityscape.

7. Kate Moss and Jessica Alba Hold Surprising Guest Records

Over the decades, the London Eye has hosted millions of riders, including an impressive list of international celebrities and royalty. British supermodel Kate Moss holds the official record for the most visits by a UK celebrity, having ridden the wheel 25 times. Meanwhile, Hollywood actress Jessica Alba holds the record for the most rides by an American celebrity, completing 31 rotations. Celebrities frequently book private capsules for quiet sight-seeing away from public crowds, though some simply join regular public queues. Royalty, rock stars, and world leaders have all taken a turn on London's famous wheel.

8. A Single Rotation Holds as Many People as 11 Double-Decker Buses

Despite its sleek appearance, the London Eye is a high-capacity transport system capable of moving thousands of people every hour. Each of the 32 glass capsules can comfortably accommodate up to 25 passengers inside its climate-controlled interior. When fully loaded, a single 30-minute revolution carries roughly 800 people around the circle. This passenger capacity is equivalent to filling 11 iconic red London double-decker buses to maximum capacity. Overall, the wheel transports over 10,000 visitors on a busy day, dwarfing the capacity of traditional amusement park rides.

9. It Uses Eco-Friendly Lubricant to Protect the River Thames

Turning a 2,100-tonne steel structure requires powerful hydraulic motors and vast amounts of industrial lubricant to keep mechanical parts operating smoothly. Because the structure sits directly adjacent to the River Thames, environmental engineers had to account for potential ecological damage. To prevent harm to marine life, the maintenance team uses special biodegradable oil throughout the mechanical systems. In the event of an accidental leak, the non-toxic fluid breaks down naturally in water without poisoning local fish or plant life. This eco-friendly innovation ensures the attraction operates without harming the delicate river ecosystem.

10. Victorian London Had Its Own Forgotten Giant Wheel in 1895

The London Eye was not the first massive observation wheel to tower over the British capital's skyline. In 1895, engineers built "The Great Wheel" at Earl's Court for the Empire of India Exhibition, standing 94 meters (308 feet) tall. Inspired by the original Chicago Ferris Wheel, the Victorian structure carried over 2.5 million passengers during its eleven-year lifespan. However, the attraction suffered multiple mechanical failures, including a notorious 1896 incident where passengers were trapped overnight. The Great Wheel was eventually demolished in 1907 after proving unprofitable to maintain, long before the London Eye resurrected the concept.

11. Its High-Tech LED Lighting Can Produce Millions of Colors

When the wheel first opened, technicians had to manually change color gels over fluorescent tubes to alter its nighttime illumination. In 2006, the lighting system underwent a massive technological upgrade to custom digital LED fixtures. Controlled by central computer software, the new lighting rig can display intricate dynamic patterns and millions of distinct color combinations instantly. The wheel is regularly lit in specific colors to mark major international events, national holidays, and charitable causes. During New Year's Eve celebrations, the lights sync directly with London's famous midnight fireworks display.

12. It Attracts More Paid Visitors Annually Than the Taj Mahal

Welcoming more than 3.75 million visitors every year, the London Eye is the most popular paid tourist attraction in the United Kingdom. Its annual attendance consistently outpaces world-famous historic sites such as the Taj Mahal in India and the Pyramids of Giza in Egypt. The wheel's prime position on the South Bank makes it a central hub for London tourism, drawing millions to the surrounding riverfront. Its commercial success proved that modern architectural engineering could create a tourist landmark capable of competing with ancient wonders.

13. It Was Built Horizontally on Barges Floating on the River

Constructing a giant observation wheel in the heart of dense central London presented immense logistical challenges for engineers. Rather than building the structure upright, construction crews assembled the steel wheel horizontally on massive floating barges anchored in the River Thames. Once assembled flat over the water, giant cranes slowly lifted the entire 1,200-tonne rim upright at a rate of just two degrees per hour until it reached a vertical angle. This extraordinary engineering maneuver took over a week to complete and drew huge crowds along the riverbank.

14. Couples Can Book "Cupid’s Capsule" for Weddings and Proposals

Beyond standard sightseeing tours, the London Eye offers customized VIP packages inside dedicated private capsules. The most famous offering is "Cupid’s Capsule," a private luxury experience popular for romantic marriage proposals and anniversary dates. Couples receive a personal host, chilled champagne, and luxury artisan chocolates while enjoying uninterrupted 360-degree views of the capital. The attraction is even licensed for official civil marriage ceremonies, allowing couples to exchange vows 135 meters above the city.

15. It Was Conceived by a Husband-and-Wife Architecture Team

The iconic landmark was designed by husband-and-wife architects David Marks and Julia Barfield of Marks Barfield Architects. They originally submitted the bold concept to a 1993 competition run by a national newspaper seeking ideas for a landmark to mark the year 2000. Although the competition produced no formal winner, the couple refused to give up on their vision and spent years securing private backing. Former British Prime Minister Tony Blair officially opened the structure on December 31, 1999, ushering in the new millennium with their visionary design.
