Nowadays clockmakers climb the Elizabeth Tower 3 times a week to wind Big Ben's Сlock, whose timing can be affected by the weather, atmospheric pressure or simply by its age. Big Ben’s Сlock is over 150 years old.
At the top of the Elizabeth Tower there is a lantern known as the Ayrton Light, which is lit whenever the House of Commons or the House of Lords is in session.

The clockmakers wind up the clock in the Elizabeth Tower every day.
