Happy Birthday Big Ben
The bell was cast on 10 April 1856 in Stockton-on-Tees by a company called Warner's of Cripplegate.
Big Ben is the world's largest four-faced, chiming clock and is attached to the Houses of Parliament in London.
The clock offically became operational on 7 September 1859.
Below are some interesting facts about the working of the clock over the years.
