The London Eye is a large metal Ferris wheel. It is also known as the Millennium Wheel and is one of the largest observation wheels in the world. Since mid-January 2015 it has been known in branding as the Coca-Cola London Eye, after an agreement signed in September 2014. The London Eye is at the western end of Jubilee Garden, on the South Bank of the river Thames, between Westminster Bridge and Hungerford Bridge.
