It is a common misconception that "Big Ben" was the official name of the entire structure; it is actually the nickname for the Great Bell inside. However, the tower itself was originally known simply as the Clock Tower. In 2012, the name was officially changed to the Elizabeth Tower to honor Queen Elizabeth II on the occasion of her Diamond Jubilee. The decision was made by the House of Commons Commission to recognize her 60 years of service to the United Kingdom. While the world still affectionately refers to the landmark as "Big Ben," the change ensures the tower's formal title reflects its royal significance. The renovation completed in recent years has even restored the clock faces to their original Victorian Prussian blue, making the Elizabeth Tower a vibrant and historically accurate centerpiece of the London skyline in 2026.
