About Big Ben
Big Ben is often thought to be the name of the iconic clock tower of the Houses of Parliament.
In fact, “Big Ben” is the nickname of one of the bells of this clock tower, originally called the Great Bell. It is unclear exactly where the name Big Ben originated, although it is thought that it was probably named after Sir Benjamin Hall, the man in charge of commissioning the structure. Another popular, although less likely, theory is that it was named after Ben Caunt, a champion heavyweight boxer of the mid nineteenth century.
In any event, most people now think of the whole of the clock tower as Big Ben. The clock tower of Big Ben was begun in 1843 and completed in 1859, while the clock was completed later that year and first sounded its bells on 7 September.
