London's annual New Year's Eve fireworks display uses Big Ben as the main countdown clock.
The clock tower's chimes signal midnight, while fireworks are launched around the London Eye and along the River Thames. Big Ben is technically the nickname of the Great Bell inside the Elizabeth Tower, although the name is commonly used for the whole clock tower. Its midnight chimes provide the audible moment that links the countdown to the start of the new year.
The large televised fireworks event began in its modern form at the turn of the millennium and developed into a major ticketed celebration. The fireworks are associated with several central London landmarks, which can cause confusion about the countdown clock. The London Eye is a principal launch and viewing landmark, but it is not the name of the clock that marks midnight.
