Big Ben is the nickname for the Great Bell of the clock at the north end of the Palace of Westminster in London and is usually extended to refer to both the clock and the clock tower as well. The tower is officially known as Elizabeth Tower, renamed to celebrate the Diamond Jubilee of Elizabeth II in 2012; previously, it was known simply as the Clock Tower.
The Elizabeth Tower and Great Bell have been scheduled for a major renovation which is expected to last three years and is due to begin in early 2017. Essential maintenance will be carried out on the clock mechanism, which will be stopped for several months during which there will be no chimes. Striking and tolling will however be maintained for important events.
The aim of the renovation is to repair and conserve the tower, upgrade facilities as necessary, and to ensure its integrity for future generations. The last significant renovation work was carried out to the tower over 30 years ago in 1983-85. The most significant addition to the tower in the forthcoming works will be the addition of a lift.
