Big Ben is a popular tourist name for the clock tower of Westminster Palace. The official name of the tower since 2011 is Elizabeth Tower . At the moment, big Ben watches are being restored until 2020. Initially, "big Ben" was the name of the largest of the six bells, but often this name is mistakenly attributed to the clock, and to the clock tower as a whole.

At the time of casting, big Ben was the largest and heaviest bell in the United Kingdom. Its weight was 13.7 tons. In 1881, the bell gave way to The big Floor.
