Big Ben

The Bell, Not the Tower (and Why Getting That Right Changes the Whole Visit)

Stand on Westminster Bridge at half past six on a weekday morning and the city is almost yours. Delivery vans on the Embankment, a few joggers on the South Bank path, the Thames moving in that flat grey way it has before the light gets going. Then the clock mechanism grinds into life above you, and the Great Bell releases a note so deep and so physical that you feel it in your chest before you hear it with your ears. Four hundred tonnes of Victorian Gothic rising ninety-six metres above Parliament Square, and for a moment you understand why Londoners struggle to explain what this place means to them. It is simply the sound of London, broadcast live on BBC Radio 4 at the top of every hour.

Here is the thing most people visiting do not know before they arrive, and it matters for understanding what you are actually looking at. Big Ben is the bell. Specifically, it is the Great Bell inside the tower, a 13.7-tonne cast-iron instrument that sounds the note E natural. The tower itself has been called Elizabeth Tower since June 2012, renamed to mark the Diamond Jubilee of Queen Elizabeth II. Before that, for over 150 years, it had no official name at all. Most Londoners still say “Big Ben” and mean the whole structure, which is fine, but knowing the distinction puts you in a different conversation with the place.

A Bell That Cracked Twice and Still Became Famous

The history of the Great Bell is a sequence of engineering failures that ended in triumph, which makes it considerably more interesting than the standard version you get on a tourist leaflet.

The first Big Ben was cast in 1856 by John Warner and Sons in Stockton-on-Tees, then dragged through the streets of London on a cart pulled by sixteen horses to be hauled up into the unfinished tower. It cracked during testing in October 1857, probably because Edmund Beckett Denison, the barrister-turned-amateur-clockmaker who oversaw the project with forensic stubbornness, had doubled the weight of the striking hammer from 355 kilograms to 660 kilograms. The recriminations were significant. The bell was broken up, the metal sent to the Whitechapel Bell Foundry in east London, and a second bell cast in April 1858.

The replacement was lighter by about two tonnes, weighed just over 13.5 tons, and sounded the intended E natural note. It was hauled up into the belfry and struck for the first time on 11 July 1859. By September of that same year, it had also cracked, this time under the hammer during normal operation. The Astronomer Royal, George Airy, proposed the solution that is still in use today: rotate the bell ninety degrees so a different part of its surface takes the blow, fit a lighter hammer, and cut a small square hole in the crack to stop it propagating further. That is what visitors are looking at when they peer up at the bell on a tour. The crack is still there. The bell has been ringing on a rotated axis since 1863, which is why one face shows considerably more wear than the others.

The clock mechanism itself was designed by Denison and George Airy together, and it remains one of the most precise large public clocks ever built. Timekeeping is regulated by a stack of old pennies placed on the pendulum. Adding a penny raises the beat by four tenths of a second per day. Removing one slows it by the same amount. The mechanism has been adjusted this way for over 160 years.

The Restoration: What Changed and What Was Revealed

Between 2017 and 2022, the Elizabeth Tower underwent a five-year conservation programme that scaffolded it so comprehensively that the clock faces disappeared from view for much of that period, a source of genuine distress for Londoners accustomed to seeing them from the South Bank. The chimes fell silent for extended periods, returning properly in November 2021 for Remembrance Sunday, which felt appropriate.

The restoration revealed something that had been hidden for nearly a century. Analysis of accumulated paint layers, six different colour schemes applied over 160 years, showed that the original Victorian clock dials were not black as they had appeared since the 1930s. They were Prussian blue. The dials had been painted black after the 1930s to mask the accumulated grime of London’s industrial air pollution, and nobody had stripped back far enough to find the original colour until now. The hands and dials were restored to Prussian blue with gold decoration, and 1,296 individual pieces of glass in the clock faces were removed and replaced with mouth-blown glass made in Germany, then cut and fitted by hand in London.

The result, when the scaffolding came down in August 2022, was a tower that looks substantially more vivid than most Londoners had ever seen it. The blue is deeper and richer than photographs suggest, particularly in afternoon light from the west. If you grew up with black dials as your reference point, the current tower looks slightly wrong and completely right at the same time.

The Ayrton Light: A Signal Between a Queen and Her Parliament

Look at the top of the tower on any evening when the House of Commons or House of Lords is sitting and you will see a light burning in the lantern above the belfry. That is the Ayrton Light, and it has a specific origin story.

Queen Victoria, working from Buckingham Palace roughly a mile to the west, asked for some way to know whether Parliament was in session without sending a messenger. In 1885, a lantern was installed at the top of the tower to serve as a signal. It was named after Acton Smee Ayrton, a Liberal politician who had served as First Commissioner of Works in the early 1870s and had overseen considerable work on the Palace of Westminster. The light was initially powered by gas jets, converted to electricity in 1903, and switched off on 1 September 1939 when blackout regulations came into force to prevent the tower from acting as a navigation marker for German aircraft. It was restored after the war and continues to operate exactly as Victoria intended.

If you cross Westminster Bridge after dark on an evening when Parliament is sitting, the Ayrton Light burns steady in the lantern above the clock faces. It is one of the simplest and most quietly functional signals in London, and almost nobody on the bridge knows what it means.

The Tower Leans. Slightly, Safely, and Forever.

The Elizabeth Tower tilts 0.26 degrees to the north-west, a displacement of roughly 500 millimetres at its tip. This is not a crisis. Structural engineers estimate the lean will not become a structural problem for somewhere between four thousand and ten thousand years.

The lean has two causes. The foundations sit on London Clay, a notoriously compressible substrate that shifts under heavy Victorian buildings, and the clay has been compressing unevenly since 1859. The second cause is more recent: the construction of the Westminster section of the Jubilee Line extension in the 1990s required tunnelling close to the foundations, which changed the ground conditions further. Thousands of tonnes of concrete were pumped into the ground to stabilise the tower during that work, and the lean has been closely monitored ever since.

You cannot see the lean with the naked eye from street level. What you can notice, if you are looking for it, is that photographs from directly south on Westminster Bridge show the tower slightly off-true against the vertical edge of Portcullis House to the east. This is not a bad thing to know about before you arrive.

Seeing It: The Free Version is Actually Better

For the overwhelming majority of visitors, the best version of Elizabeth Tower is experienced from outside and at no cost. The question is not whether to pay, but where to stand.

Westminster Bridge is the correct starting point. The midpoint of the bridge, on the upstream (eastern) side, gives you the full tower over the river with room to compose a photograph properly. The stone balustrade acts as a leading line into the frame. Come before 8am on a weekday and the bridge will have a handful of people on it rather than the solid mass of tourists it accumulates by mid-morning. The light at that hour, particularly in spring and early summer, catches the Prussian blue dials from the north-east and makes them glow.

The view most visitors miss is from below the bridge, not on it. There is a walkway at river level on the South Bank side that passes under the arch of Westminster Bridge. Standing at water level beneath the bridge and looking west toward the tower, you get a perspective that street photography almost never shows: the tower rising above the parapet of the bridge, with the Thames foreground. This requires going down the steps on the South Bank end.

The Albert Embankment on the opposite (south) bank, walking east from Lambeth Bridge toward Westminster, gives a long lateral view of the tower over the water with Lambeth Palace in the background. The gardens of St Thomas’ Hospital, just east of Westminster Bridge on the South Bank, are frequently overlooked and offer a direct west-facing sightline with benches and considerably fewer people than the bridge itself.

Parliament Square, on the north side, gives you the tower against the sky without the river. The statues around the square, Winston Churchill nearest to Parliament, Nelson Mandela facing the Palace of Westminster, Mahatma Gandhi at the north-west corner, create useful foreground elements for photographs and are worth reading as a curatorial argument about who gets commemorated in this particular space.

For night photography, the illuminated clock faces reflecting in the Thames from Westminster Bridge are the reliable option. The Ayrton Light, if Parliament is sitting, adds a secondary point of light above the belfry that most evening photographs ignore.

Going Inside: The 334-Step Reality

The tour up Elizabeth Tower is restricted to UK residents only, no exceptions, and it requires contacting your Member of Parliament to request an invitation. This is not a bureaucratic hurdle but a practical one: the tower has no lift, no accessible alternative, and the 334 steps constitute a serious climb through increasingly narrow spiral staircases. The minimum age is eleven. Ear defenders are provided for the belfry level because the bells, at close range, produce sound levels that can cause immediate hearing damage.

From August 2026, tickets for the tour cost 55 pounds for adults and 35 pounds for children aged eleven to seventeen. The tour lasts up to ninety minutes. Tickets are released three months in advance, on the second Wednesday of each month at 10am London time, and popular dates sell out quickly. If you are a UK resident and want to do this, contact your MP’s office several months ahead.

The tour takes you through the mechanism room where the clock’s workings are visible at close range, past the four clock faces seen from inside, and up to the belfry where the bells hang. The Great Bell up close is not elegant. It is enormous, cracked, worn on one quadrant from 160 years of hammer strikes, and entirely convincing as the object whose sound has ordered time for London since 1859.

Westminster Abbey and the Churchill War Rooms: Do Both

The Elizabeth Tower is the centrepiece but the neighbourhood is extraordinarily dense with serious things to see within a fifteen-minute walk.

Westminster Abbey, ten minutes north-west, is the coronation church for every English and British monarch since William the Conqueror in 1066. This is not just a historical statistic. The Coronation Chair, a wooden throne made in 1300 and used at every coronation since 1308 with two exceptions, sits in the Abbey and can be seen on a standard visit. Poets’ Corner contains the graves or memorials of Chaucer, Dickens, Hardy, Tennyson, and T.S. Eliot, among others. Adult tickets run around 29 pounds for self-guided entry. Book online in advance, particularly during summer and school holidays. The Abbey is closed to tourists on Sundays, when it operates as a working church, so plan accordingly.

The Churchill War Rooms are a short walk east along King Charles Street, directly underneath the Treasury building. The underground complex operated as the nerve centre of British wartime government from 1939 to 1945. When it was sealed after the war, it was preserved essentially as it was left: the map room, the transatlantic telephone booth, Churchill’s bedroom, the dining room. The Cabinet War Rooms are less theatrical than they sound and more affecting than you expect. Adult tickets start at 33 pounds. Allow at least two hours. The museum is operated by the Imperial War Museums and the audio guide is included in the ticket price.

The walk from Westminster Bridge north through Parliament Square to Westminster Abbey and then east to the Churchill War Rooms covers the core of the area in under a kilometre. Do it in that order, with the Abbey first and the War Rooms second, ending on King Charles Street so you can walk out into St James’s Park for some space afterward.

Getting There: Westminster Tube, Not Waterloo

Westminster Underground station is on the Circle and District lines, with an exit onto Bridge Street directly at the foot of the tower. This is the correct station. Do not use Waterloo (fifteen minutes’ walk across the bridge) unless you are arriving from the South Bank Eurostar side and want the walk. Do not use Victoria (twenty minutes on foot west) unless you are combining with Buckingham Palace.

The station itself is worth a brief look if you have not seen it before. It was rebuilt for the Jubilee Line extension in the late 1990s by architect Michael Hopkins, and the exposed concrete of the deep-level platforms, arranged around a grid of coffers that climb four storeys to the surface, is one of the more genuinely impressive pieces of underground architecture in London.

If you are cycling, there are Santander Cycles docking stations along the Embankment and on Bridge Street. The riverside path on the Embankment runs uninterrupted from Blackfriars to Vauxhall Bridge and makes for a practical approach from either direction.

Buses stop on Bridge Street and Parliament Square from multiple directions. Walking from Victoria station along Birdcage Walk through St James’s Park is a pleasant approach that deposits you at Parliament Square from the west.

Where to Eat: Be Honest About the Options

Westminster is not a neighbourhood where restaurants cluster because of local appetite. It is a government district surrounded by tourist sites, and a lot of what is available reflects that geography: cafeterias, tourist-facing chains, and a few solid places that survive because civil servants and parliamentary staff eat there year-round.

The best of the accessible options near the tower is Blue Boar, the pub and dining room in the Conrad Hotel on Marsham Street, about ten minutes’ walk south-east of Parliament Square. The menu runs to proper Scotch eggs, good pies, and a short list of well-sourced mains without pretension. It is more expensive than a pub but less expensive than a restaurant, and the quality is consistent. Budget around 20 to 30 pounds per person for a full meal with a drink.

Mio Restaurant on Great Peter Street, a few minutes south-west, is a straightforward Italian with a short menu and reasonable prices. The pasta is made fresh, the room is quiet enough for a conversation, and the portions are generous. Around 15 to 25 pounds per person, considerably less at lunch.

The Churchill War Rooms has a cafe in the basement that is decent for a light lunch, with the considerable advantage of not requiring you to go back outside. The food is simple, the seating predictable, and the proximity to the exhibition means you can break your visit cleanly.

For something worth going slightly out of your way for, Emilia’s Crafted Pasta on Victoria Street opened in 2025 and features a live pasta-making station that produces fresh pasta cut to order. It is informal, the queue moves quickly, and the food is several levels above tourist-district average. Budget around 20 pounds per person.

Avoid the immediate perimeter of Parliament Square for food. The options there are geared toward people who need to eat immediately and cheaply, and you can do better with five minutes of walking in any direction.

A Few Things Most Guides Do Not Tell You

The clock mechanism is regulated by stacking old penny coins on the pendulum. One penny changes the rate by four-tenths of a second per day. The clockmakers who look after the mechanism have been making these adjustments since the clock first ran in 1859.

The Prussian blue colour on the clock dials is not a renovation choice or a design decision. It is the original specification, recovered by stripping back paint layers applied over more than a century. The black that most people alive today grew up seeing was the result of 1930s grime management, not Victorian aesthetics.

The Jubilee Line extension tunnelling in the 1990s made the tower lean more than it already did, required pumping thousands of tonnes of concrete into the ground to prevent further movement, and is the primary reason the lean now stands at 0.26 degrees rather than the shallower angle it had before.

The Ayrton Light was originally installed because Queen Victoria wanted to see from Buckingham Palace whether Parliament was in session. The light has been answering that question, in one form or another, since 1885.

The first Big Ben cracked during testing before it ever rang publicly. The second Big Ben also cracked within months of being hung in the belfry. The bell that Londoners hear today has been ringing on a ninety-degree rotation from its intended position since 1863, and the crack that caused the problem is still there, visible on a tour.

The Practical Summary

Westminster Tube (Circle and District lines), exit directly onto Bridge Street. The tower is free to look at from any angle outside. Tours are UK residents only, require an MP’s invitation, cost 55 pounds for adults from August 2026, and should be requested several months ahead. Minimum age eleven, no lift, 334 steps.

For photographs: weekday mornings before 8am on Westminster Bridge, or at water level below the bridge on the South Bank walkway, or from the St Thomas’ Hospital gardens. For night shots: from Westminster Bridge with the illuminated dials and, if Parliament is sitting, the Ayrton Light above.

Combine with Westminster Abbey (book tickets online, closed Sundays to tourists) and the Churchill War Rooms (33 pounds adults, allow two hours). Plan to eat at Blue Boar or walk five minutes to find something better than the Parliament Square perimeter offers. Give yourself at least half a day for the area, and accept that the tower looks better in person than in any photograph you have seen of it.

The specific tip worth remembering before you go: arrive on Westminster Bridge before 7am if you want the full tower more or less to yourself, with good light and room to think. By 9am the bridge belongs to everyone else, which is fine, but the early version is better.
