![]() The design for the current tower, known since 2012 as the Elizabeth Tower in honour of HM the Queen’s Diamond Jubilee, was only added a couple of years later, with the help of fellow architect Augustus Pugin. Do you know when Big Ben was built? Credit: AlamyĪrchitect Charles Barry’s original designs to replace the old Palace of Westminster, after the catastrophic fire of 1834, didn’t even include a clock tower. However, its journey to national treasure status has not been entirely easy. Dominating the Westminster skyline and the Houses of Parliament, it’s one of London’s most recognisable monuments. Its iconic chimes were first recorded by the BBC on New Year’s Eve in 1923 and are now recorded live by the BBC twice a day, every day, at 6pm and midnight.Īnd the clock itself, with its four, huge cast iron dials is equally famous. Since then it has become Britain’s most famous bell. So as work gets underway to restore the much-loved landmark, we thought it was time to ask: when was Big Ben built? The origins of London’s Big Benīig Ben – the name given to the great bell rather than the actual clock – was installed in the Palace of Westminster clock tower in 1859. Works include repairing the clock, as well as the fabric of the tower, and while the whole project is expected to take four years, the bongs will still sound as special events. Each penny causes Big Ben to gain 0.4 second per day.Credit: UK Parliament It is a symbol of London the world over, but do you know the origins of Big Ben? If you’ve ever asked yourself, ‘when was Big Ben built?’ then read on for a potted history of our most famous landmarkīig Ben has been telling the time for Londoners since the mid 19th century and is now undergoing essential maintenance that has meant Big Ben’s bongs have fallen silent. ![]() The pendulum is adjusted by adding pennies made before the decimalization of the United Kingdom’s currency in 1971 to the weight. Big Ben is accurate to within two seconds per week. Big Ben is wound three times a week, and the winding takes over an hour. The double three-legged gravity escapement designed by Denison for Big Ben achieves the second of these but not the first. An ideal escapement would transmit the impulse without interfering with the free swing, and the impulse should be as uniform as possible. In a pendulum clock an escape wheel is allowed to rotate through the pitch of one tooth for each double swing of the pendulum and to transmit an impulse to the pendulum to keep it swinging. Denison’s principal contribution was a novel gravity escapement that imparted unprecedented accuracy to the clock. The clock was designed by Edmund Beckett Denison (later Sir Edmund Beckett and Lord Grimthorpe) in association with Sir George Airy (then astronomer royal) and the clockmaker Edward Dent.
