City of London (Bank of England, Museum of London, Tower Bridge, Tower of London, St Paul's Cathedral)The City is where London originally developed within the Roman city walls and is a city in its own right, separate from the rest of London.It is now the most important financial centre in the world, but an area where modern skyscrapers stand next to medieval churches on ancient street layouts.Today, London has taken on a much larger meaning to include all of the vast central parts of the modern metropolis, with the city having absorbed numerous surrounding towns and villages over the centuries, including large portions of the surrounding "home counties", one of which - Middlesex - being completely consumed by the growing metropolis.
East (City Airport, Queen Elizabeth Olympic Park, West Ham United FC, Westfield Stratford City)Originally part of the county of Essex, taking in former industrial areas on the upper Thames Estuary, while to the north east lies the gateway to the affluent Epping Forest area.
West (Chiswick House, Heathrow Airport, Musical Museum, Osterley Park, Syon Park)Taking in much of the ancient English county of Middlesex (which many local residents still identify with rather than "London") and former parts of Buckinghamshire.
The Mayor of London is elected by London residents and should not be confused with the Lord Mayor of the City of London.
The names of several boroughs, such as Westminster or Camden, are well-known, others less so, such as Wandsworth or Lewisham.
North (Alexandra Palace, Harrow School, RAF Museum, Tottenham Hotspur FC, Wembley Stadium)Largely made up of lush green middle-class suburbs, many of which were formerly part of the counties of Middlesex, Hertfordshire and Buckinghamshire before being absorbed into Greater London.
South (Chessington World of Adventures, Chislehurst Caves, Down House)Containing many commuter suburbs formerly belonging to the counties Kent and Surrey with housing in varying styles, as well as the buzzing urban centres of Sutton, Kingston upon Thames, Croydon and Bromley.
South Kensington-Chelsea (Kensington Palace, Natural History Museum, Royal Albert Hall, Science Museum, Victoria and Albert Museum)An extremely well-heeled inner London district with famous department stores, Hyde Park and Kensington Gardens, many museums and the King's Road.
Westminster (Buckingham Palace, Downing Street, Horse Guards, Houses of Parliament, Tate Britain, Westminster Abbey, Westminster Cathedral)The seat of government and an almost endless list of historical and cultural sights.
Once the stalking ground of Jack the Ripper, now home to hipstery bars, art galleries and parks, and an extremely diverse population.
