Trivia
Technically, "Big Ben" is the name of the clock's hour bell (said to have been named after Victorian heavyweight boxing champion Ben Caunt), whilst the clock itself is the Great Westminster Clock and the tower was renamed in 2012 as the Elizabeth Tower, in honour of Queen Elizabeth II's Diamond Jubilee. However, in practice "Big Ben" has always been used interchangeably for all three.
