where is london located in the world map
London Standing on the River Thames in the south east of the island of Great Britain, London has been a major settlement for two millennia. It was founded by the Romans, who named it Londinium.[9] London's ancient core, the City of London, largely retains its 1.12-square-mile (2.9Â km2) medieval boundaries. Since at least the 19th century, "London" has also referred to the metropolis around this core, historically split between Middlesex, Essex, Surrey, Kent, and Hertfordshire,[10][11][12] which today largely makes up Greater London,[13][14][note 1] a region governed by the Mayor of London and the London Assembly.[15][note 2][16]
