London Map

• Greater London is the top-level administrative subdivision covering London. The small, ancient City of London at its core once contained the whole settlement, but as the urban area grew the City Corporation resisted attempts to amalgamate it with its suburbs, causing "London" to be defined in a number ways for different purposes; and the situation was once open to legal debate. Forty per cent of Greater London is covered by the London post town, within which 'LONDON' forms part of postal addresses.

• The London telephone area code (020) covers a larger area, similar in size to Greater London, although some outer districts are omitted and some places just outside are included. The area within the orbital M25 motorway is normally what is referred to as 'London'. and the Greater London boundary has been aligned to it in places.

• Outward urban expansion is now prevented by the Metropolitan Green Belt, although the built-up area extends beyond the boundary in places, resulting in a separately defined Greater London Urban Area. Beyond this is the vast London commuter belt. Greater London is split for some purposes into Inner London and Outer London. The city is split by the River Thames into North and South, with an informal Central London area in its interior. The coordinates of the nominal centre of London, traditionally considered to be the original Eleanor Cross at Charing Cross near the junction of Trafalgar Square and Whitehall, are approximately 51°30′26″N 00°07′39″W / 51.50722°N 0.1275°W / 51.50722; -0.1275.

• London is a major international air transport hub with the largest city airspace in the world. Eight airports use the word London in their name, but most traffic passes through only five. London Heathrow Airport, in Hillingdon, West London, is the busiest airport in the world for international traffic, and is the major hub of the nation's flag carrier, British Airways. In March 2008 its fifth terminal was opened. There were plans for a third runway and a sixth terminal however these were cancelled by the Coalition Government on 12 May 2010. Similar traffic, with the addition of some low-cost short-haul flights, is also handled at London Gatwick Airport, located south of London in West Sussex.

• Stansted Airport, situated north east of London in Essex, is the main UK hub for Ryanair and Luton Airport to the north of London in Bedfordshire, caters mostly for low-cost short-haul flights. London City Airport, the smallest and most central airport, is focused on business travellers, with a mixture of full service short-haul scheduled flights and considerable business jet traffic.

• Snow is relatively uncommon, particularly because heat from the urban area can make London up to 5 °C (9 °F) warmer than the surrounding areas in winter. however at some light snow showers are seen and are very common during cold snaps with at least one very heavy snowfall event a year. The February 2009 Great Britain and Ireland snowfall was the heaviest London had seen for 18 years.

• London is in USDA Hardiness zone 9, and AHS Heat Zone 2. Although extreme weather does not happen very often, deep depressions have been known to pass through like the Great Storm of 1987. Tornados are rare, but the Kensal Green area of the city was hit by the 2006 London tornado causing £10 million of damage and injuring 6 people.

• In the second half of the 19th century and the first half of the 20th, London was noted for its dense fogs and smogs. Following the deadly Great Smog of 1952, the Clean Air Act 1956 was passed, leading to the decline of such severe pollution in the capital. Nevertheless, in 2010 the City of London was ranked as one of the most polluted places in Europe.

• London's bus network is one of the largest in the world, running 24 hours a day, with 8,000 buses, 700 bus routes, and over 6 million passenger journeys made every weekday. In 2003, the network's ridership was estimated at over 1.5 billion passenger trips per annum, more than the Underground. Around £850 million is taken in revenue each year. London has the largest wheelchair accessible network in the world and, from the 3rd quarter of 2007, became more accessible to hearing and visually impaired passengers as audio-visual announcements were introduced. The distinctive red double-decker buses are internationally recognised, and are a trademark of London transport along with black cabs and the Tube.

• London has a modern tram network, known as Tramlink, based in Croydon in South London. The network has 39 stops, three routes and carried 26.5 million people in 2008. Since June 2008 Transport for London has completely owned Tramlink and plans to spend £54m by 2015 on maintenance, renewals, upgrades and capacity enhancements. Since April 2009 all trams have been refurbished.

• London has hosted the Summer Olympics twice, in 1908 and 1948. In July 2005 London was chosen to host the Olympic and Paralympic Games in 2012, which will make it the first city in the world to host the Summer Olympics three times. London was also the host of the British Empire Games in 1934. London's most popular sport is football and it has fourteen League football clubs, including five in the Premier League: Arsenal, Chelsea, Fulham, Queens Park Rangers and Tottenham Hotspur.

• London also has four rugby union teams in the Aviva Premiership (London Irish, Saracens, Wasps and Harlequins), although only the Harlequins play in London (all the other three now play outside Greater London, although Saracens still play within the M25). The other professional rugby union team in the city is second division club London Welsh, that plays home matches in the city. The city has other very traditional rugby union clubs, famously London Scottish, Richmond F.C., Rosslyn Park F.C.,Westcombe Park R.F.C. and Blackheath F.C..

• There are currently two professional rugby league clubs in London – Harlequins Rugby League who play in the European Super League at The Stoop and the Championship One side the London Skolars (based in Wood Green, London Borough of Haringey).

• From 1924, the original Wembley Stadium was the home of the English national football team, and served as the venue for the FA Cup final as well as rugby league's Challenge Cup final. The new Wembley Stadium serves exactly the same purposes and has a capacity of 90,000. Twickenham Stadium in south-west London is the national rugby union stadium, and has a capacity of 84,000 now that the new south stand has been completed.

• Cricket in London is served by two Test cricket grounds Lord's (home of Middlesex C.C.C) in St John's Wood and the Oval (home of Surrey C.C.C) in Kennington. Lord's has hosted four finals of the cricket world cups. One of London's best-known annual sports competitions is the Wimbledon Tennis Championships, held at the All England Club in the south-western suburb of Wimbledon. Other key events are the annual mass-participation London Marathon which sees some 35,000 runners attempt a 26.2 miles (42.2 km) course around the city, and the Oxford and Cambridge Boat Race on the River Thames between Putney and Mortlake.
