It was reported that the clock is wound up by hand three times a week on Monday, Wednesday and Friday, a process that takes more than an hour because it is not possible to wind while it is chiming.
The Big Ben was commissioned as part of the rebuilding exercise of the Palace of Westminster after the fire of 1834. It was a brainchild of Edmund Beckett Denison, a leading barrister and gifted amateur horologist together with Clockmaker, Edward Dent.
It is stated that the Big Ben will continue to work for many years to come.
