All my life I thought Big Ben was a famous clock tower in London. I was absolutely sure of it and had even taught that fact to others. Then I went to London and found out that Big Ben is actually the nickname of the largest bell inside the tower, which is now called the Elizabeth Tower in honor of the Diamond Jubilee of Queen Elizabeth II. And if we are going to get picky, it’s not even officially in London, but rather in Westminster. In that moment, the bell and the tower had not changed, but my understanding certainly did.
