Cleaning the Great Clock

Back in 2007 a team of specialist industrial rope access technicians abseiled down the south clock face of Big Ben (nickname), they then began the task of cleaning and repairing the four faces of the clock seen by so many as a symbol of central London. This  work was the final phase of a programme of planned works preparing what is officially known as the Great Clock for its 150th anniversary in 2009.

The clock earns its nickname from the 13.5 tonne bell that rings out the famous chimes. It is named after Sir Benjamin Hall, the man who was Commissioner of Works when the bell was first installed in 1859.

The clock has been stopped accidentally over the years by weather, workmen, breakages and even birds, but technicians have always been able to get it going again.
