The old city and really beautiful one in Europe is none other than London. 7 million people live in London. Some enjoy living in London some hate to visit and think wastage of time and money and some have mixed reactions.  If we look at the history, London was the most important city in Britain. May be because of excellent climate conditions and a good place for trade and business. London was rebuilt after the event of Great Fire took place in 1666 and that rebuild was amazing, wonderful and no one could stop it. Acres of expensive residential development resulted in the great squares and elegant streets west of the city. Manufacturing and other trades including fishing were evident and enjoy. Today the memories of all London's past can be found in the modern city where recent changes are also evident. People migrated in large numbers to London and rich personalities cleared all the poor areas to make it more beautiful. But as we know everywhere problems never leaves you so problems exist in London also but you can not deny the history, architecture, culture and interest.
