A sprawling metropolis, London is a mishmash of cultures and creeds, leafy parks and
cultural hot spots. It's home to Her Majesty the Queen, whose residence at
Buckingham Palace is among the capital's must-sees. Topshop, Harvey Nichols and
a multitude of markets feed Londoners' retail addiction. The stock exchange is
one of the most important in the world, and the city is an international media center,
home to the Financial Times, BBC, Thomson Reuters, Bloomberg Europe and the Economist,
among others. A third of the world's largest companies make their headquarters
in London, which is projected to have the fourth-largest city economy by 2020.
