The London Eye, London, UK

The London Eye, sometimes called the Millennium Wheel, is the largest observation wheel in the world (though often erroneously called a Ferris wheel), and has been since its opening at the end of 1999. It stands 135 metres (443 feet) high on the western end of Jubilee Gardens, on the South Bank of the River Thames in Lambeth, London, England, between Westminster and Hungerford Bridges. It is adjacent to London's County Hall, and stands opposite the offices of the Ministry of Defence situated in Westminster which it overlooks to the west.
