At London's New Year's Eve fireworks, the famous clock tower traditionally shown near the countdown is Elizabeth Tower.
Elizabeth Tower stands at the north end of the Palace of Westminster and contains the Great Clock. Its largest bell is Big Ben, although “Big Ben” properly refers to the bell rather than the tower itself. That distinction is one of the most common mix-ups in descriptions of London celebrations.
The tower was completed in the nineteenth century as part of Charles Barry and Augustus Pugin's Palace of Westminster rebuilding. It became an internationally recognizable symbol of London because of its clock faces, chimes, and position beside the River Thames.
London's modern New Year's Eve display centers on fireworks launched around the London Eye and the Thames. Television coverage often combines those views with Elizabeth Tower and its midnight chimes, making the tower a visual marker of the year's change.
