“At the present rate, it will be 10,000 years before we reach that,” he added, referring to comparisons with the tower in Pisa, Italy.Įven so, the tilt might now be just about visible to the naked eye. “We’re talking about unbelievably small movements,” said John Burland, an engineering professor at Imperial College London who has been involved in the study on the tower. Like many old buildings, its position has been shifting imperceptibly for years due to environmental factors such as seasonal temperature and moisture level changes. The clock tower - colloquially known as Big Ben after its massive bell - has been slightly off centre since it was erected in the mid-19th century. It would take thousands of years before the London landmark’s tilt matches that of the Leaning Tower of Pisa. The 96-meter tower is leaning in the northwest direction at an angle of 0.26 degrees, according to a report from 2009 that was recently obtained by the Sunday Telegraph through a Freedom of Information request.īut there’s no cause for alarm, experts said. Documents recently published by Britain’s Parliament show that the top of its gilded spire is nearly half a meter out of line. The hammer, which hit the bell, was too heavy.Experts say the neogothic clock tower - one of the world’s most recognizable landmarks - is gently leaning to one side. Why did a crack appear when Big Ben was struck in 1858? No change to the bell whatsoever because it's become the familiar, the familiar note.Ī much-loved building largely hidden for the past few years, slowly revealing itself once more. It should be 'E' - the note E, but it does give it a slightly flat sound, a very serious sound, in fact. The hammer was too heavy, but it gives the bell its unique tone. This crack appeared when Big Ben was struck during a test in 1858. There's one piece of damage here that’s been deliberately left alone. We are standing in the belfry of the Elizabeth Tower, and it was specially constructed so that the chiming bells for the four quarters could be heard right across London. With the clock mechanism out of action, a computerised system has meant that on special occasions, Big Ben has still been struck. But during the refurbishment, as many layers of paint were stripped away, it became clear that they were originally this shade of blue - it's called Prussian Blue, and that is what they have been repainted in. Just like filters, you can customize the specific parameters to shape your own sounds. For many years, the minute demarcations, the numbers and the clock hands were painted black. One of the most striking things you notice is the colour of the clock faces. Working on this clock would be a once in a lifetime opportunity - to actually have taken it all to pieces, putting it back together again, and then carry on looking after it for a few more years - that's just going to be fantastic. ![]() This is one of the bits that we couldn't actually get to and service while the minute hands were on.
