Which New Year's Eve event in London is centered on the chimes of Big Ben?

London New Year's Eve is centered on the midnight chimes associated with Big Ben. The celebration includes a major fireworks display along the River Thames, with the London Eye and the Palace of Westminster among the best-known visual landmarks.

Big Ben is the nickname commonly used for the great bell in the Elizabeth Tower, although many people use the name for the tower or clock as a whole. The clock tower stands beside the Palace of Westminster. At midnight, its chimes provide the audible signal for the start of the new year in the United Kingdom.

London's modern organized fireworks celebration developed in the twenty-first century and is staged along the Thames. It should not be confused with the annual New Year's Day parade, which takes place on January 1 and follows a different route and format. The fireworks event also requires controlled viewing areas and ticket arrangements in central London.
