The Elizabeth Tower, commonly known as Big Ben, represents one of London’s most enduring symbols and serves as the clock tower of the Palace of Westminster. Rising 316 feet above the Thames, this Gothic Revival masterpiece has marked time for the capital since 1859, though the tower itself was completed in 1843 following the devastating fire that destroyed much of the old Palace of Westminster in 1834.
The tower bears the name of Queen Elizabeth II, renamed in 2012 to mark her Diamond Jubilee, though most visitors continue to refer to it by its popular moniker. Big Ben technically refers to the largest of the five bells housed within the belfry, weighing 13.76 tonnes and named after Sir Benjamin Hall, the Commissioner of Works when the bell was installed. The Great Clock mechanism, designed by Edmund Beckett Denison, maintains remarkable accuracy and has become synonymous with British punctuality and parliamentary democracy.
Architect Augustus Pugin designed the tower’s intricate Gothic details, while Charles Barry oversaw the broader Palace of Westminster reconstruction. The tower’s cast-iron spire and four clock faces, each measuring seven metres in diameter, demonstrate Victorian engineering prowess. The hour hand measures 2.7 metres in length, while the minute hand extends 4.3 metres, making the timepiece visible from considerable distances across central London.
Interior tours of Elizabeth Tower resumed in 2023 following extensive restoration work that began in 2017. The renovation addressed structural concerns, mechanical updates to the clock mechanism, and conservation of the tower’s stonework and metalwork. Visitors must climb 334 steps to reach the belfry, as no lift operates within the tower. The ascent typically requires 45 minutes to one hour, including guided commentary about the tower’s history, clock mechanics, and parliamentary functions.
Tour capacity remains limited, with groups restricted to eight people maximum. Booking opens several months in advance through UK Parliament’s official website, and tours frequently reach full capacity within hours of release. UK residents and overseas visitors follow the same booking process, though separate allocation systems operate for each category. Tours operate on select days, typically excluding parliamentary sitting periods and major ceremonial occasions.
The restoration project temporarily silenced Big Ben’s regular chimes, though the bells continue to mark New Year and significant national events. Normal hourly chiming resumed progressively throughout 2023 as mechanical testing concluded. The famous BBC radio time signal, broadcast since 1924, continues to feature Big Ben’s chimes, maintaining the tradition that connects the tower to households across Britain and the Commonwealth.
Visitors unable to secure tower tours can appreciate Elizabeth Tower’s exterior from multiple vantage points around Westminster. Parliament Square provides the classic perspective for photographs, while Westminster Bridge offers elevated views across the Thames. The nearby Palace of Westminster and Westminster Abbey create a concentrated area of historical significance, making efficient use of time for first-time visitors to London.
Photography restrictions apply within the tower during tours, though external photography faces no limitations. Security screening procedures similar to airport protocols apply before entering any part of the Palace of Westminster complex. Tour participants should expect metal detectors and bag searches, adding approximately 15 minutes to arrival times.
