Big Ben
People think that Big Ben is the name of the clock tower
that stands at the North end of the Houses of Parliament.
In reality, it is the nickname given to the great bell in the
tower. Nevertheless, most people today think of the whole
clock when they think of Big Ben.
A clock tower was originally built on the site in 1288, but it
was destroyed when the Palace of Westminster burned down
in 1834. The new clock tower which houses Big Ben was
built and first started working in 1859. It is the largest four-
faced clock in the world and the third largest free-standing
clock tower, standing at 96.3 metres high..
Big Ben is famous for its reliability. It keeps very accurate
time and rarely breaks or stops. Its mechanism was specially
designed so that its speed can be changed by adding or
removing a penny coin. This alters the time by 0.4 seconds a
day.
During World War One, the clock faces, which are normally
lit up, were darkened and the bells silenced to prevent attack
by German zeppelin ships. During World War Two, only the
clock was darkened and Big Ben continued to ring. In 1941
the clock tower was hit by a German bomb. Amazingly,
the clock continued to work. On New Year's Eve, 1962, ice
and snow made the hour and minute hand slow down.This
caused the bell to ring in the New Year ten minutes late.
In 1976, after over one hundred years of use, the clock mechanism broke down, and in May
2005 the clock stopped for a short while because the weather was too hot. This doesn't
happen very often in England. Although Big Ben was voted the most popular landmark in
London, it's not actually possible to walk up the tower. This is only allowed for VIP guests of
the parliament. Most visitors usually look up at the clock from the ground and enjoying the
sound of its great bell - Big Ben.
