The London Eye, the biggest ferris wheel in Europe, is celebrating its tenth birthday these days. It was built to celebrate the 2000 Millenium, but it was not until March 2000 when it was open to the public. It's 135 metres tall and it's got 32 egg-shaped passenger capsules, each of which can fit up to 25 people. It moves so slowly that it doesn't have to stop to let people on and off.
More than 36 million passengers have travelled in it: it's become one of the main attractions in London, ant it's even a romantic place because many people have got married on board.
