For a long time, London was a small city. All its people lived
inside the walls that were built by the Romans. This area is still called the
City of London. There were many villages around the city. Gradually, more
people came to live there. Then, step by step, the villages joined together
into one huge city.
The city has a huge network of transport systems. The Victorians
built a number of railway systems in the mid-19th century. Their main stations
are in London, and the lines go to every corner of Great Britain. There were
originally five major companies, which were merged into a national rail network
in modern times.
There is also the world's first underground railway system, London
Underground, which is the main way commuters get into London. There are five
airports, though only one is actually in London (London City Airport). There is
the London end of the London–Birmingham canal, which was important to the
industrial 19th century.
Most people in London are British. However, London also has many
immigrants. These people come from many different countries. They speak many
different languages and have different religions and cultures. There are also
many people from different countries who stay in London on business. Many
people visit London as tourists. They may see the famous "Sights of
London". These sights include palaces, churches and museums.
London is one of the world's most important cities for business,
finance, and politics. It is also important for culture: media, entertainment,
fashion, and art.
