Don't call it Big Ben—it's now Elizabeth Tower! Parliament just approved the London landmark's renaming in honor of Queen Elizabeth's Diamond Jubilee—her 60th year on the throne. Fun fact: "Ben" only refers to the giant bell at the top of the tower, though the nickname has extended to the entire structure in recent years. So technically, it hasn't had a proper name until now—and perfect timing, too. Congrats, Lilibet! Click through for our favorite moments from the Diamond Jubilee.
