The Houses of Parliament and Elizabeth Tower, commonly called Big Ben, are among London's most iconic landmarks. Technically, Big Ben is the name given to the massive bell inside the clock tower, which weighs more than 13 tons (13,760 kg). The clock tower looks spectacular at night when the four clock faces are illuminated.

The History of Big Ben
The Palace of Westminster was destroyed by fire in 1834. In 1844, it was decided the new buildings for the Houses of Parliament should include a tower and a clock.
A massive bell was required and the first attempt (made by John Warner & Sons at Stockton-on-Tees) cracked irreparably. The metal was melted down and the bell recast in Whitechapel in 1858. Big Ben first rang across Westminster on 31 May 1859. A short time later, in September 1859, Big Ben cracked. A lighter hammer was fitted and the bell rotated to present an undamaged section to the hammer. This is the bell as we hear it today.

London's Favourite Landmark: Why Ben?
The origin of the name Big Ben is not known, although two different theories exist.
- The first is that is was named after Sir Benjamin Hall, the first commissioner of works, a large man who was known affectionately in the house as "Big Ben".
- The second theory is that it was named after a heavyweight boxing champion at that time, Benjamin Caunt. Also known as "Big Ben", this nickname was commonly bestowed in society to anything that was the heaviest in its class.
