History of the Big Ben

The story behind Big Ben is quite an interesting. In 1834 Westminster Palace was destroyed by fire. A decade later it was decided that the new building for the House of Parliament should have a tower that would include a clock. There was more than one attempt to make a massive bell by John Warner and Sons at Stockton-on-Tees. The massive original bell cracked so it was melted down and replaced with a new bell in Whitechapel in 1858. A year later on May 31, the bell rang for the first time in Westminster. Many months later in September the bell cracked again so the hammer was replaced with a lighter one and the bell was just rotated so the damaged side could not be seen. This is the same bell is rings every hour today.

Great Bell

The Great Bell is really known by it’s nickname Big Ben, which is the largest bell in the tower and is part of the Great Clock of Westminster. The very first bell weighed 16 tons and was cast by John Warner and Sons. The bell was named in honor of Sir Benjamin Hall, and his name is inscribed on it but some people like to believe the name came from a heavyweight boxer named Benjamin Caunt. Some people think that the original name of the bell should be Royal Victoria or Victoria to show respect for Queen Victoria. Before the tower was finished the bell was placed in New Palace Yard. Later, the first bell was moved to the tower on a trolley which was drawn by 16 horses followed by a cheering crowd. Unfortunately, as mentioned earlier, the bell was cracked beyond repair while being tested so it had to be replaced. The new bell was installed on April 1858.

Movement of Clock

The clock’s movement is most famous for being very reliable. Edmund Beckett Denison and George Airy were the designers of the movements of the clock but the construction was completed by clockmaker Edward John Dent. Before completion of the work, Edward John Dent died and his stepson Frederick Dent finished the project for him in 1854. Since the tower was not completed until 1859 he had enough time to experiment with different things. So the pendulum was installed within an enclosed windproof box that was underneath the clock room. It is 13 feet long, weighs 660 pounds and beats every 2 seconds. On top of the pendulum is a small stack of pennies that was used to adjust the time of the clock. Each penny had an important role because removing or adding a penny would change the clock’s speed by at least 0.4 seconds a day.
