The Big Ben is the nickname extended to the Clock Tower built in London in 1858. This tower that has officially been known as the Elizabeth Tower since 2012, is the second largest four-facing tower in the world. The total height of the tower is 96 metres. The movement of the clock, and also the chimes of the bell are known for their reliability.
Amazing Fact: In 1949, the clock had slowed down by 4 ½ minutes because a flock of starlings had perched on the minute hand!
