London is one of the world's greatest cities. Diverse, ethnically and linguistically, it offers an intoxicating mix of grandeur, history, style and culture. From ancient streets, leafy parks and grand architecture to iconic landmarks, neon lights, world class shopping and a cool arts scene, there's nowhere in the world quite like this thriving metropolis. Visitors typically spend most of their time in and around the West End, where London's main attractions -- Piccadilly Circus, Charing Cross Road's book shops, Covent Garden, Soho, Regent and Oxford Streets, Trafalgar Square, Leicester Square, Carnaby Street -- are located. Farther west are the pricier neighborhoods of Belgravia, Kensington (Kensington Palace, Albert Memorial, Royal Albert Hall), South Kensington (Science Museum, Natural History Museum, Victoria and Albert Museum), Knightsbridge (Harrods, Harvey Nichols), Mayfair, Chelsea (Kings Road) and Notting Hill (Portobello Road).
The City of London's financial district (home to St. Paul's Cathedral, Fleet Street, Tower of London) is a must for history lovers. In medieval times, the City constituted most of London, but over the years, urban areas sprawled far beyond. As the City's boundaries have remained almost unchanged since the Middle Ages, it is now only a tiny part of the metropolis, though holds city status in its own right.
