Elizabeth Tower was the name given in 2012 to the London clock tower famous for its New Year's Eve chimes.
The tower stands at the north end of the Palace of Westminster in London. It contains the Great Clock of Westminster and the bell commonly called Big Ben. Technically, Big Ben is the name of the great bell, not the tower itself, although everyday usage often applies the name to the entire landmark.
The tower was renamed Elizabeth Tower in June 2012 to mark Queen Elizabeth II's Diamond Jubilee. Before that, it was generally called the Clock Tower. Its clock began keeping time in 1859, and the tower's distinctive Gothic Revival design was created by Charles Barry and Augustus Pugin.
The quarter bells sound before the hour, while the great bell marks the hour. Broadcast chimes from Westminster have made the clock an enduring feature of New Year's Eve coverage in the United Kingdom.
