No, Big Ben is not the real name of the famous clock tower in London; it is actually the nickname for the Great Bell housed within the tower. The tower itself was officially known as the Clock Tower for over 150 years until it was renamed the Elizabeth Tower in 2012 to commemorate the Diamond Jubilee of Queen Elizabeth II. In 2026, while almost everyone globally still refers to the landmark as "Big Ben," locals and historians are increasingly using the correct name, Elizabeth Tower, especially following the extensive multi-year restoration that concluded in the early 2020s. The bell itself weighs 13.7 tonnes and is famous for its "E-natural" chime. The nickname "Big Ben" is thought to be named after either Sir Benjamin Hall, who oversaw the bell's installation, or Benjamin Caunt, a champion heavyweight boxer. Despite the official nomenclature, the term "Big Ben" has become an inseparable part of the London brand and the most iconic symbol of British parliamentary democracy.
