One of the best known landmarks in London city is the Clock Tower of the Palace of Westminster. The Big Ben, named after Sir Benjamin Hall, the first Commissioner of Works, is the largest hour bell of the other five quarter bells. It is located in the northern side of the extended building stretched alongside the river Thames. Initially, John Warner & Sons casted a 16 ton weighing bell as the clock tower’s hour bell. The clock tower wasn’t yet complete by then; they hung the bell in the Palace yard on a temporary basis.
This however, resulted in a crack in the bell itself, repeatedly twice, which eventually was recast as a 13.5 ton bell, in the Whitechapel Bell Foundry in 1858 and in July, 1859 the crack was being repaired and a light hammer was provided to avoid any further cracks. The world’s largest clock is of 25ft diameter, the hour hand and minute hand being 9ft and 14ft respectively, was designed by Edmund Beckett Denison, is identified for its impeccable steadfastness and accuracy. It survived the infamous bombing of the World War II, which even destroyed the House of Commons. Constructed between 1843 and 1858, the clock tower is officially known as St. Stephen’s Tower.
