Why Big Ben Will Never Stop Ticking
On of the most iconic monuments in Britain, Big Ben has come to symbolise the sights and sounds of a nation but ever-needy machinery.
Its attachment to Britain's parliament building means that making sure it remains reliable is Big Ben's greatest challenge.
Following her 150th anniversary, the keepers of Big Ben must ensure the monument stays clean, timely and most importantly, does not stop at an inopportune moment.
Political elections, and royal and state visits alike all pass below its famed clock faces. But as history continues to be made on its doorstep, workers behind the scenes must do everything from keeping pigeons at bay with a Harris Hawk patrol, to monitoring a rather worrying tilt.
