While popularly known as Big Ben, the iconic clock tower at the north end of the Palace of Westminster was formally renamed the Elizabeth Tower in 2012 to mark the Diamond Jubilee of Queen Elizabeth II. Strictly speaking, "Big Ben" refers only to the Great Bell housed within the tower, which weighs 13.7 metric tons. In 2026, following the completion of its major multi-year restoration, the tower stands as a high-fidelity masterpiece of Gothic Revival architecture. For 2026 tourists, visiting the Elizabeth Tower is a high-value necessity; while the nickname Big Ben is used almost universally by the public, the official high-fidelity name honors the longest-reigning monarch in British history. The tower's four clock faces have been returned to their original Prussian blue and gold color scheme, providing a high-fidelity visual experience for those viewing the London skyline from Westminster Bridge or the South Bank.
