Текст:
London, the capital of the UK, was founded in AD 43 by the Roman
invaders as a settlement and a fortress. At first it had the name of
Londinium. Due to its convenient position in the mouth of the river
Thames the settlement grew and developed into a city. In the 11th
century London became the capital of England. For centuries it was a
prominent port through which wealth and prosperity came to the country.
Being an important trade and political centre, the city enjoyed greater
independence than the other cities of the medieval England and even
had the right to elect the head of the city, Lord Mayor. The picturesque
ceremony of the elections of Lord Mayor of London is still held every
year and attracts thousands of tourists.
The city was built rather chaotically, the streets being narrow and
dirty. It grew and developed together with the developing of the nation.
In 1666 the Great Fire of London destroyed the most part of the city,
which was rebuilt, but the old planning remained untouched.
Historically and geographically London can be divided into three
parts: the City, the West End and the East End. The City is the financial
centre of the country, with offices of large firms and banks and the
Stock Exchange.
The West End has always been considered a place where aristocrats
lived. There is a great number of sights and attractions: the Houses of
Parliament, Westminster Abbey, St Paul’s Cathedral, the Nelson Column,
to mention just a few of them. London’s beautiful parks are also there:
Hyde Park, St. James’ Park, Regent’s Park are favourite places for
Londoners to visit and relax. One may also go shopping in the West
End — Piccadilly Street and Oxford Street both present a wide choice
of expensive shops and boutiques.
The East End was previously considered the place where not wellto-do people lived. The identity of the East End as a place of deprivation
and poverty persisted until well after the Second World War, becoming
overlaid with certain gangster glamour in the 1960s. At the beginning of
the twenty-first century, London east of the City is still seen as having
a different character, claiming a certain independence of look from the
rest of metropolis; but its cultural status has been transformed. Parts of
the East End are believed to house the highest population of artists in
Europe, and the East End is now considered a bohemian district. The
ugly docks, which for years disguised the face of the East End, are now
closed, and new hotels, stadiums and apartment houses are being built.
Now London extends much more than the City, the West End and
the East End. Its suburbs grow rapidly. London and its suburbs are
called Greater London.
As well as it is impossible to say that Moscow is a typical Russian
city, nobody can call London a typical British one. In fact, it has become
a multinational metropolis, being inhabited by people from all over the
world. It is always busy and crowded. It certainly has its own face —
millions of faces. Maybe, this is the reason why people say: “When a
man is tired of London, he is tired of life.”
