Home of some of the most expensive apartments in the world, Knightsbridge is probably most famous as the site of the department store to end all department stores - Harrods, and its so-glamorous-it-hurts Harvey Nichols. Only the seriously wealthy need apply. Imposing Victorian architecture and superb garden squares mix with the top fashion shops in the capital, and more than make up for the swathes of tourists that mill around Knightsbridge.

DID YOU KNOW that until 1902 Harrods sold pure cocaine to the public?
