Big Ben
The Elizabeth Tower is over  high and the turret clock mechanism that drives the clock alone weighs about 5 tons (5.08 tonnes). The clock on it has four faces that are  in diameter, making it one of the largest in the world for a clock that chimes and strikes every hour. The figures on the clock face are about  long and the minute spaces are  long. There are, however, clocks with much bigger faces that Big Ben. One of these is the Abraj Al Bait, a hotel in Mecca, Saudi Arabia. Its faces are more than ten times bigger than Big Ben.
