Big Ben
Big Ben, which tolls the hour at the Palace of Westminster, was cast in 1858 and rung for the first time on 31 May 1859. "Big Ben" weighs 13½ tons and is the largest bell ever cast at the foundry. This bell also cracked because too heavy a hammer was initially used. The crack and the subsequent retuning gives Big Ben its present distinctive tone. A profile template of Big Ben surrounds the entrance door of the Whitechapel Foundry, while the original moulding gauge is retained near the furnaces. The final bill for Big Ben came to £572.
