LONDON, ENGLAND - MAY 30: A general view of the Houses of Parliament and the London Eye on May 30, 2012 in London, England. A full rotation of the giant Ferris wheel, the largest of it's kind in Europe, takes 30 minutes and rises to a height of 135 metres. On a clear day one can see for 40km from the top.
