The London Eye
The London Eye is the tallest observation wheel in the world (135 metres or 443 feet high) and is the United Kingdom's most popular paid for visitor attraction. It has been called the finest and most popular new attraction in London since the Great Exhibition. It has over 3.5 million visitors per year.
It opened in March 2000 as part of the celebrations to mark the Millennium and was originally called the Millennium Wheel. It was designed by husband and wife team David Marks and Julia Barfield. The main sponsor was British Airways; it was owned by them, the architects and The Tussauds Group. In November 2005, it was sold to the Merlin Entertainments Group Company and its name was changed.
