What is Big Ben?
Big Ben is the name of the great bell, the biggest bell within the clock tower of the Palace of Westminster at the Houses of Parliament in London.
It weighs approx 13.5 tonnes & was cast in 1856. Amongst other bells, Big Ben rings out striking each hour on the hour.
Big Ben is often wrongly used to name the clock (which is the biggest 4 face chiming clock in the world).
Big Ben, nicknamed after Sir Benjamin Hall, a popular member of Parliament of the time and commissioner of works, is now more commonly known as the complete clock and tower as well as the bell.
In September 2012 the Clock tower was renamed 'Elizabeth Tower' in honour and celebration of the queens Diamond Jubilee.
