Big Ben

Commonly called Big Ben, this name properly applies to the Great Bell housed within the clock tower at the north end of the Palace of Westminster. The tower itself, known as Elizabeth Tower, contains a four-faced clock that began operation in 1859 and is one of London’s most recognisable landmarks.

The clock faces and bell are the principal attractions; the tower’s Gothic Revival architecture is visible from many points along the Thames and nearby bridges. The bell sounds on the hour and the quarter bells mark the quarter hours, forming an audible landmark across the local area.

Constructed in the mid-19th century as part of the rebuilt Palace of Westminster, the tower and clock mechanism have undergone maintenance and conservation while continuing to function as part of the parliamentary estate. Public interior tours are restricted and generally arranged through Members of Parliament for UK residents.

Situated at the edge of the River Thames in Westminster, the tower stands adjacent to the Houses of Parliament and across from Westminster Bridge, within easy reach of central London transport links.

• Name note: Technically the name refers to the Great Bell; the clock tower itself is officially called Elizabeth Tower, renamed in 2012 to mark the Diamond Jubilee.
• Practical info: The tower rises to about 96 metres and the bell traditionally chimes on the hour; viewing and photography are best from Westminster Bridge and the Parliament forecourt.
