LONDON, ENGLAND – MARCH 22: St Stephen’s Tower, also known as ‘Big Ben,’ rises in front of the London Eye on March 22, 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.
