History: London, England, United Kingdom

The Thames Barrier was completed in the 1980s to protect London against tidal surges from the North Sea. The Greater London Council was abolished in 1986, which left London as the only large metropolis in the world without a central administration. In 2000, London-wide government was restored, with the creation of the Greater London Authority. To celebrate the start of the 21st century, the Millennium Dome, London Eye and Millenium Bridge were constructed. On 7 July 2005, several London Underground trains and a bus were bombed in a series of terrorist attacks.
