At London's New Year's Eve celebrations, Big Ben is the famous clock tower landmark commonly shown near the countdown.
Big Ben is technically the nickname of the Great Bell inside the Elizabeth Tower at the Palace of Westminster. In everyday speech, however, “Big Ben” is often used for the entire tower. The bell's midnight chime provides an important audio signal for the start of the new year when it is operating normally.
London's large fireworks display is staged along the River Thames, with views around the London Eye and Westminster. The event became a major annual public spectacle in the early twenty-first century, with ticketed viewing areas introduced for crowd management.
The Elizabeth Tower underwent major conservation work beginning in 2017, and the bell's regular public striking was limited during parts of the restoration. This explains why archived footage and live broadcasts may not always show the same sound or lighting conditions.
