Big Ben

The Clock Tower is the world's largest four faced, chiming clock. The structure is situated at the north eastern end of the Houses of Parliament building in Westminster, London. It is often referred to as "Big Ben" which is actually the main bell housed within the Clock Tower. The Clock Tower has also been referred to as The Tower of Big Ben and, incorrectly, St Stephen's Tower, which is actually the spired tower towards the middle of the Palace and is also the main point of entry for attendees of debates and committees.
