Big Ben

							    Big Ben

The Clock Tower is a turret clock structure at the north-
eastern end of the Houses of Parliament building in
Westminster, London, England. It is popularly known as Big
Ben, but this name is actually a nickname for the clock's
main bell. The tower has also been referred to as St.
Stephen's Tower or The Tower of Big Ben, in reference to its
bell.
                      Clock faces
The clock faces were once large enough to allow the Clock Tower to be the
   largest four-faced clock in the world, but have since been outdone by the
   Allen-Bradley Clock Tower in Milwaukee, Wisconsin. The builders of the
   Allen-Bradley Clock Tower did not add chimes to the clock, so the Great
   Clock of Westminster still holds the title of the "world's largest four-faced
   chiming clock." The clock mechanism itself was completed by 1854, but
   the tower was not fully constructed until four years later in 1858.
   Houses of Parliament
 During the second world war in 1941, an incendiary bomb
  destroyed the Commons chamber of the Houses of Parliament,
  but the clock tower remained intact and Big Ben continued to
  keep time and strike away the hours, its unique sound was
  broadcast to the nation and around the world, a welcome
  reassurance of hope to all who heard it.
 There are even cells within the clock tower where Members of
  Parliament can be imprisoned for a breach of parliamentary
  privilege, though this is rare; the last recorded case was in 1880.
 The tower is not open to the general public, but those with a
  "special interest" may arrange a visit to the top of the Clock Tower
  through their local (UK) MP.
