This month the London Eye will welcome its 25 millionth to the South Bank. The attraction is celebrating the milestone with an online photography competition.
Visitors from the last 7 years are invited to share their memories and upload their photos from the London Eye via the website www.londoneye.com/photography
Since opening in 2000 an average of 1,000 visitors an hour have stepped into one of the Eye's 32 capsules.
3.5 million visitors a year take in the sights of the capital from the observation wheel.
The competition will be live for a month. One winning photo, chosen by a panel of judges, will be framed on permanent display at the British Airways London Eye ticket office inside County Hall.
The winning photographer will also receive a year's pass to all Tussauds Group attractions and a bottle of Laurent-Perrier champagne. All photos entered will become part of a mosaic which will be on permanent display at the ticket office.
