Big Ben is not the name of the clock or the tower. It is the name of it''s 13 ton bell named after Sir Benjamin Hall, a London politician of the time.
Big Ben first started working in1859. Its tower is nearly100 meters high and the clock face is about 8 meters wide. The minute hand is about 4 meters long.
This amazing clock stopped on May 29th , 2005. It was 10:20 p.m. and the hands only started to move again 90 minutes later. Some people think it was because of the unusual hot weather. But maybe the old machine is just tired.
Well, that''s it for now. Have a wonderful time here in London.
