*************

Big Ben is the nickname for the great bell of the clock at the north end of the Palace of Westminster in London,^[1] and is often extended to refer to the clock or the clock tower as well.^[2] Big Ben is the largest four-faced chiming clock and the third-tallest free-standing clock tower in the world.^[3] It celebrated its 150th anniversary in May 2009 (the clock itself first ticking on 31 May 1859),^[4] during which celebratory events took place.^[5][6]

The nearest London Underground station is Westminster on the Circle, District and Jubilee lines.

The clock is famous for its reliability. The designers were the lawyer and amateur horologist Edmund Beckett Denison, and George Airy, the Astronomer Royal. Construction was entrusted to clockmaker Edward John Dent; after his death in 1853 his stepson Frederick Dent completed the work, in 1854.^[13] As the Tower was not complete until 1859, Denison had time to experiment: Instead of using the deadbeat escapement and remontoire as originally designed, Denison invented the double three-legged gravity escapement. This escapement provides the best separation between pendulum and clock mechanism. The pendulum is installed within an enclosed windproof box sunk beneath the clockroom. It is 3.9m long, weighs 300 kg and beats every 2 seconds. The clockwork mechanism in a room below weighs 5 tons. On top of the pendulum is a small stack of old penny coins; these are to adjust the time of the clock. Adding a coin has the effect of minutely lifting the position of the pendulum's centre of mass, reducing the effective length of the pendulum rod and hence increasing the rate at which the pendulum swings. Adding or removing a penny will change the clock's speed by 0.4 second per day.^[6]

On 10 May 1941, a German bombing raid damaged two of the clockfaces and sections of the tower's stepped roof and destroyed the House of Commons chamber. Architect Sir Giles Gilbert Scott designed a new five-floor block. Two floors are occupied by the current chamber which was used for the first time on 26 October 1950. Despite the heavy bombing the clock ran accurately and chimed throughout the Blitz.
