Big Ben is one of London's best-known landmarks, which is {#blank#}1{#/blank#} nickname of a bell hanging in the clock tower
at the {#blank#}2{#/blank#} (north) end of the Houses of Parliament in
Westminster, London. Some believe it got {#blank#}3{#/blank#} (it) name from Sir Benjamin Hall. Officially,
the tower itself is called Elizabeth Tower. It was {#blank#}4{#/blank#} (previous) known as just the Clock Tower, but
was renamed in September 2012 in honor of Queen Elizabeth II. However, most
people, {#blank#}5{#/blank#} (include) those that live in London, call the
tower "Big Ben", because it is very large.
Designed by Edmund Beckett Denison, the clock took 13 years
to build and it {#blank#}6{#/blank#} (complete) in 1859. It has worked continuously
since then except for a few months in 1976 when it {#blank#}7{#/blank#} (break) down and had to be fixed. Since August
2017, repair work is being done on the clock, which will take four years. For
the {#blank#}8{#/blank#} (safe) of those doing this work, Big Ben no
longer rings out every hour. It will still be heard {#blank#}9{#/blank#} special occasions, such as the New Year and
Remembrance Day.
The Elizabeth Tower has become one of the most important {#blank#}10{#/blank#} (symbol) of the United Kingdom and is often in
the establishing shot of films set in London.
