Why is there more than one clock in the House of Representatives, behind the Speaker's chair?
Thanks for your question, Catherine. This was a tricky one and we had to go to the Serjeant-at-Arms for some help.
Parliament House has close to 2600 clocks. They all tell the time and most of them are also used to signal divisions in the Senate and the House of Representatives.
But the clocks in the Senate and House are different from other clocks in the building. They tell the time and count down the time left to give a speech.
The reason there are 2 clocks behind the Speaker of the House of Representatives’s chair is so that the space is symmetrical. Symmetry is an important part of the design of Parliament House.
