In fact, this tower is called Saint Stephens Tower, but people, even those who live in the UK, are used to calling it "Big Ben." Actually, Big Ben is the huge bell inside the building. Its weight is about thirteen tons and it rings every hour daily: once at one o'clock, twice at two o'clock and so on. However, people who live near the tower can hear at New Year’s Night how the bell strikes thirteen. It’s considered to be the biggest bell ever made in the country.
