Palace of Westminster

A working Parliament beside the Thames

The Palace of Westminster stands on the north bank of the River Thames in central London. It is the meeting place of the UK Parliament’s House of Commons and House of Lords, which is why the building is commonly called the Houses of Parliament. The familiar silhouette belongs to a working political institution as much as to a landmark: debates, ceremonies and public business continue inside a complex that has developed over many centuries.

The site’s royal history reaches back to the eleventh century, when a palace was established at Westminster. Parliament met there from the thirteenth century, and Westminster Hall became one of the most important surviving parts of the medieval complex. The Palace now seen from the river is largely a nineteenth-century rebuilding, but it incorporates older fabric and occupies a place at the centre of British constitutional history.

UNESCO does not list the Palace in isolation. The World Heritage property, inscribed in 1987, also includes Westminster Abbey and the medieval church of St Margaret’s. Together, the three buildings represent the intertwined histories of monarchy, religion and parliamentary government. The river setting and the close relationship between the institutions are part of the heritage value, so the best first impression comes from looking at the wider group rather than treating the clock tower as the whole site.

Fire, rebuilding and Gothic Revival

A major fire on 16 October 1834 destroyed most of the old Palace. The official parliamentary account explains that underfloor stoves used to dispose of the Exchequer’s tally sticks ignited panelling in the Lords Chamber. Westminster Hall survived, along with the Undercroft Chapel, the cloisters and Chapter House of St Stephen’s, and the separate Jewel Tower. The disaster erased much of the medieval complex but left a small number of buildings that still anchor a visitor’s understanding of the earlier site.

A competition selected Charles Barry’s design for a new Palace in the Gothic Revival style. Augustus Welby Pugin contributed architectural details and much of the interior design. The first stone was laid in 1840; the parliamentary chronology records the rebuilding as complete in 1870, although decorative and other work continued beyond that date. The result drew on English Gothic forms while creating a highly organised modern home for two legislative chambers, offices, courtyards and ceremonial routes.

The Palace’s towers have different functions and histories. The Elizabeth Tower contains the Great Clock and the Great Bell commonly known as Big Ben; the nickname is often applied to the tower itself, but technically refers to the bell. Westminster Hall, by contrast, preserves a medieval setting and its celebrated timber hammer-beam roof. Moving between those spaces gives the building unusual depth: a visitor can encounter both the remnant of a royal medieval hall and a Victorian vision of constitutional government.

Inside a living institution

A visit is not the same as entering a conventional museum. Parliamentary business may affect which rooms are open, when tours run and what security procedures apply. In 2026, Parliament advertised guided tours on Saturdays and selected weekdays, as well as self-guided audio tours that include the Commons and Lords chambers when available. The programme changes with the parliamentary calendar, so a past visitor’s schedule should not be treated as a promise of access on a future date.

The interiors connect architecture to the work carried out there. The Commons and Lords are separate chambers with distinct traditions, furnishings and ceremonial roles. Public tours explain how the building functions as well as how it was designed; the guide or audio narration can help distinguish areas that look similar in photographs but serve different purposes. Access to particular rooms may be restricted for parliamentary business, official events or maintenance.

Security and visitor rules are part of planning. UK Parliament recommends booking in advance to secure entry and directs visitors to current information on prices, accessibility, facilities and security screening. Arrive with enough time for the entry process and follow instructions about bags, photography and movement through the building. The Palace is a seat of government, so temporary operational requirements take precedence over a visitor itinerary.

How to plan a visit

Start with Parliament’s official visiting pages and live booking calendar. Guided and audio-tour availability, dates and prices can change; check the option that matches your interests and mobility needs before travelling. Some experiences are offered only at selected times, and tours may pause when the parliamentary schedule or building operations require it. Do not assume that the Palace is open for casual walk-in sightseeing simply because the exterior and nearby streets are accessible.

Allow time to view the exterior from several points along the Thames and Parliament Square, but follow local pedestrian and security instructions. The site is busy, and queues or street closures may affect an otherwise short walk. If you want a wider historic visit, Westminster Abbey and St Margaret’s have their own entry policies, hours and ticket arrangements; they are neighbouring components of the World Heritage property, not included automatically in a Palace tour.

The Palace of Westminster rewards attention to both detail and context. Its Gothic Revival towers have become a shorthand for national politics, yet the building also holds a medieval hall, evidence of a devastating fire and a continuing parliamentary life. Check official access information shortly before your visit, reserve ahead and leave room to notice the Thames-side setting. Understanding the Palace means seeing more than an emblem: it is an evolving workplace within a landscape shaped by centuries of power and public debate.
