Big Ben is possibly the most famous landmark in London. The 13.5 ton bell first rang out in 1859. On New Year's Eve, 1923, the bell was first heard on radio. On New Year's Eve, 1949, it was both seen and heard on television.

Big Ben is named for Sir Benjamin Hall, who was nicknamed "Big Ben" because of his size. He was the Commissioner of Works at the time the bell was installed.

The Clock Tower, which contains the famous "Big Ben" bell, is located on the eastern end of the Houses of Parliament in London, England.

The Clock Tower has 4 faces that are each 23 feet wide. The minute hands are each 14 feet in length, and the four dials on the clock measure 22 feet in diameter. Each dial contains 365 panes of glass, one for each day of the year. The clock connected to Big Ben is famous for its accuracy. Placing pennies inside the mechanism controls the Clock's accuracy.
