The London Eye, located on the southern bank of the River Thames adjacent to Westminster Bridge, is the tallest Ferris wheel in Europe, and the most popular paid tourist attraction in the United Kingdom, visited by over 3.5 million people annually.
The Eye is 135 metres (443 feet) high and rotates at less than 1mph, meaning an entire revolution takes around 30 minutes. Visitors are offered an unrivalled view of London and, on a clear day, many miles beyond.
