The London Eye, known for sponsorship reasons as the Coca-Cola London Eye, is a giant Ferris wheel on the South Bank
of the River Thames in London.The structure is 443 feet (135 m) tall and the wheel has a diameter of 394 feet (120 m).
When it opened to the public in 2000 it was the world's tallest Ferris wheel.
Its height was surpassed by the 525-foot (160 m) Star of Nanchang in 2006, the 541-foot (165 m) Singapore Flyer in 2008,
and the 550-foot (167.6 m) High Roller (Las Vegas) in 2014. Supported by an A-frame on one side only, unlike the taller
Nanchang and Singapore wheels, the Eye is described by its operators as "the world's tallest cantilevered observation wheel".
