The London Eye, or the Millennium Wheel, is a cantilevered observation wheel on the South Bank of the River Thames in London. It is Europe's tallest cantilevered observation wheel, and the most popular paid tourist attraction in the United Kingdom with over three million visitors annually. It has made many appearances in popular culture. The structure is tall and the wheel has a diameter of . When it opened to the public in 2000 it was the world's tallest Ferris wheel. Its height was surpassed by the Sun of Moscow in 2022, the Star of Nanchang in 2006, the Singapore Flyer in 2008, the High Roller (Las Vegas) in 2014, and the Ain Dubai in 2021. Supported by an A-frame on one side only, unlike these taller examples, the Eye is described by its operators as "the world's tallest cantilevered observation wheel". The Eye offered the highest public viewing point in London until it was superseded by the observation deck on the 72nd floor of The Shard in early 2013. The London Eye adjoins the western end of Jubilee Gardens (previously the site of the former Dome of Discovery), on the South Bank of the River Thames between Westminster Bridge and Hungerford Bridge beside County Hall, in the London Borough of Lambeth. The nearest tube station is Waterloo. History Design and construction The London Eye was designed by the husband-and-wife team of Julia Barfield and David Marks of Marks Barfield Architects. Mace was responsible for construction management, with Hollandia as the main steelwork contractor and Tilbury Douglas as the civil contractor. Consulting engineers Tony Gee & Partners designed the foundation works while Beckett Rankine designed the marine works. Nathaniel Lichfield and Partners assisted The Tussauds Group in obtaining planning and listed building consent to alter the wall on the South Bank of the Thames. They also examined and reported on the implications of a Section 106 agreement attached to the original contract, and also prepared planning and listed building consent applications for the permanent retention of the attraction, which involved the co-ordination of an Environmental Statement and the production of a planning supporting statement detailing the reasons for its retention. The rim of the Eye is supported by tensioned steel cables and resembles a huge spoked bicycle wheel. The lighting was re-done with LED lighting from Color Kinetics in December 2006 to allow digital control of the lights as opposed
