Elizabeth Tower vs. Big Ben

If you ask someone to name London´s places of interest, the most popular answer will be Big Ben. But it is a common mistake. A lot of people think that popular London´s tower is called Big Ben. It is not correct. 

Big Ben is a name for the biggest of six bells within the Tower. The Tower is officially called the Elizabeth Tower, after being renamed in 2012 from "Clock Tower" to celebrate the Diamond Jubilee of the Elizabeth II. 

Yesterday we discussed this question with my pupils and made a model of Elizabeth Tower. Now I hope everyone knows for sure the difference between Big Ben and Elizabeth Tower.
