Big Ben is not the name of a man. It is a name of the clock. It is in London. London is the capital city of England. The big clock has four faces. So no matter where you stand, you can read the face of the clock. The hands are about four meter long.
If you go to London, you may want to visit the house of the Parliament. In that place you will find Big Ben sits at the top of the clock tower in the House of the Parliament. The big clock makes a very loud noise. “Ding dong. Ding dong”- the clock strikes every quarter of an hour.
