London grew up around two historic cities the City of London
and the City of Westminster. The City of Westminster began as a
residence for England's rulers. The City of Westminster stood
about 3 miles southwest of the City of London which was surround
ed by a great wall. As London grew, it spread far beyond its walls
and took in the royal City of Westminster. Today the area where
the Roman London stood is known as the City of London. It is often
called the City. These two parts are the centre of London today
Central London has tall office buildings and busy streets as well as
outstanding museums, art galleries, theatres and beautiful parks
The City is the oldest part of London. It stands where the walled
City of London stood for hundreds of years. Today it's London's
famous financial district. But it also has some reminders of its
colourful past. The great dome of St Paul's Cathedral, for example
still towers over buildings in the air
The City of Westminster is the seat of the British government
It is the oldest part of the West End. This part of London is also
known for its theatres as well as trade and nightlife
