London Eye, a giant observation wheel located in the Jubilee Gardens on the South Bank. The 135 meter (443ft) tall structure was built as part of London's millennium celebrations.

The observation wheel turns slow enough for people to embark while it is moving. A complete turn takes about 30 minutes. Thanks to the construction of the glass capsules on the outer side of the rim, the passengers have a great 360° view over London. Many famous landmarks are clearly visible, including Buckingham Palace, St. Paul's Cathedral and the Houses of Parliament. On a clear day you can see as far as 40 km (25 miles).

The total weight of the wheel and capsules is 2,100 tonnes - or as much as 1,272 London black cabs!
