London Eye

The London Eye, originally the Millennium Wheel, is a cantilevered observation wheel on the South Bank of the River Thames in London. It is the world's tallest cantilevered observation wheel, and the most popular paid tourist attraction in the United Kingdom with more than three million visitors annually. It has been featured numerous times in popular culture.

The structure is 135 metres (443 ft) tall and the wheel has a diameter of 120 metres (394 ft). When it opened to the public in 2000 it was the world's tallest Ferris wheel, until the 160-metre (525 ft) Star of Nanchang in China surpassed it in 2006. Unlike taller wheels, the Eye is cantilevered and supported solely by an A-frame on one side. The Eye was the highest public viewing point in London until 2013, when it was surpassed by the 245-metre (804 ft) View from The Shard observation deck.
