You’re standing on Westminster Bridge, the wind is whipping off the Thames, and you look up. It’s the shot everyone takes. But if you asked the person next to you how old Big Ben is, they’d probably give you the wrong answer.
Honestly, most people think the tower itself is Big Ben. It isn’t.
That’s the first hurdle. To understand the age of this London icon, we have to split it into three distinct parts: the Great Bell (the actual Big Ben), the clock mechanism, and the Elizabeth Tower that houses them. They weren't all finished at the same time. If you’re looking for a single birthday, you’re going to be disappointed because the history of this site is a messy timeline of fire, political bickering, and engineering ego.

The Night Everything Changed
The story doesn't start with a celebration. It starts with a massive inferno. On October 16, 1834, the old Palace of Westminster was basically erased from the map by a fire caused by the careless burning of old wooden tally sticks in the heating furnaces. It was a disaster. But out of those ashes, the British government decided they needed something world-class.
Charles Barry won the commission to build the new Houses of Parliament. He wasn't a clock expert, though. He brought in Augustus Pugin to design the clock tower. Pugin was a genius, but he was also struggling with his mental health toward the end of the project. He famously said, "I never worked so hard in my life for Mr. Barry," before descending into a breakdown.
The tower was finished in 1859. So, if you're counting the shell, it's roughly 167 years old as of 2026. But the heart of the tower—the bell—has a different, more dramatic birth date.
The Troubled Birth of the Great Bell
When people ask how old Big Ben is, they are technically asking about the "Great Bell." The one we hear today isn't even the first one.
The first bell was cast in 1856. It was a monster. It weighed 16 tons and was hauled through the streets of London by 16 white horses. People cheered. It was a spectacle. But there was a problem. During testing, it cracked beyond repair. They had to break it up and start over.
The second bell—the one currently hanging in the belfry—was cast on April 10, 1858, at the Whitechapel Bell Foundry. This is the "true" Big Ben. It first rang out over London on May 31, 1859.
Wait.
There's a catch. Just two months after it started ringing, this bell cracked too. For three years, Big Ben was silent. Imagine that—the most famous clock in the world, and it couldn't even chime. Eventually, they just turned the bell a quarter turn so the hammer hit a different spot, cut a small square "notch" to stop the crack from spreading, and used a lighter hammer. That’s why it has that slightly "off" E-natural note we all recognize today.
The Tech Behind the Tick
The clock mechanism itself is a masterpiece of Victorian engineering. Designed by Edmund Beckett Denison and George Airy, it was completed in 1854.
Think about that. The clock was ready five years before the tower was even finished. It sat in a workshop gathering dust because the construction of the tower was lagging so far behind. Denison was a lawyer by trade, not a clockmaker, which made the professional clockmakers of the time absolutely furious. They said his design wouldn't work. They were wrong.

His "Double Three-Legged Gravity Escapement" became the standard for high-accuracy tower clocks. It’s still there. It still works. It’s roughly 172 years old.
Restoration and the Modern Era
You might have noticed the tower looking a bit different lately. From 2017 to 2022, the tower underwent a massive £80 million renovation. This wasn't just a quick scrub.
They took the entire clock mechanism apart. Every single cog. They also fixed the "Prussian Blue" color scheme on the clock dials, which had been painted black in the 1930s to hide the soot from London’s smog. Now, it looks exactly like it did when Pugin first unveiled it.
People often wonder if the age of the tower makes it fragile. During World War II, a small bomb hit the top of the tower and destroyed the glass in one of the dials, but the clock kept ticking. It's remarkably resilient. It has survived the Great Smog, the Blitz, and decades of pigeon droppings.
Quick Timeline Reference
- 1834: The fire that necessitated the build.
- 1843: Construction begins on the new Palace of Westminster.
- 1854: The clock mechanism is completed (172 years ago).
- 1858: The current Big Ben bell is cast (168 years ago).
- 1859: The clock begins keeping time and the bell chimes for the first time.
- 2012: The tower is officially renamed the Elizabeth Tower for the Diamond Jubilee.
- 2022: Major conservation work is completed.
Why the Name Matters
"Big Ben" is the nickname. We know this. But where did it come from?
Historians are split. Some say it's named after Sir Benjamin Hall, the First Commissioner of Works, whose name is inscribed on the bell. He was a big guy. Others swear it's named after Ben Caunt, a famous heavyweight prize-fighter of the era. Honestly, it's probably Hall, but the boxing story is way more fun to tell at the pub.
Calling the tower "Big Ben" is like calling your house "The Fridge." It’s technically incorrect, but everyone knows what you mean. Since 2012, the structure is officially the Elizabeth Tower. Before that, it was just "The Clock Tower."
How Old is Big Ben in Comparison?
To give you some perspective on how old Big Ben is, let's look at other landmarks.

The Eiffel Tower didn't show up until 1889. That makes Big Ben thirty years the senior. The Statue of Liberty followed in 1886. However, compared to the Tower of London (which dates back to the 1070s) or Westminster Abbey across the street, Big Ben is actually the new kid on the block. It’s Victorian, not Medieval.
Seeing It Today
If you're planning a visit, you can't just walk in. Only UK residents can book tours through their MP, and even then, the waitlist is months long. You have to climb 334 stone steps. There is no elevator.
The climb takes you past the ventilation shaft, the clock mechanism room, and finally to the belfry. Standing next to the bell when it strikes is an experience that vibrates your entire skeletal system. It's loud. Like, "wear ear protection or lose your hearing" loud.
Things You Probably Didn't Know
- The Penny Trick: The clock's accuracy is adjusted by adding or removing old copper pennies from the pendulum. Adding a single penny speeds up the clock by 0.4 seconds per day.
- The Light at the Top: There is a light above the clock faces called the Ayrton Light. It’s lit whenever Parliament is sitting after dark. It was originally installed at the request of Queen Victoria so she could see from Buckingham Palace when her politicians were actually working.
- The Lean: The tower isn't perfectly straight. Due to ground conditions and tunneling for the Jubilee line, it leans about 0.04 degrees. It’s nowhere near Pisa-levels of tilting, but it’s there.
Actionable Tips for Your London Trip
If you want to experience the age and majesty of the tower without the crowds, here’s what you do:
- Go at night. The clock faces are illuminated by LED lights (formerly gas lamps), and the crowds on the bridge thin out significantly after 10:00 PM.
- Cross the river. The best photos aren't from the Westminster side. Walk across Westminster Bridge to the South Bank. There's a spot right by the stairs leading down to the river that frames the tower perfectly.
- Listen for the "Quarter Jacks." Big Ben only strikes on the hour. The "Westminster Chimes" you hear every 15 minutes come from the four smaller bells.
- Check the Parliament website. If you are a UK resident, check for tour openings at least six months in advance. They disappear instantly.
- Use a real camera. Smartphones struggle with the scale and the backlighting of the clock faces at sunset. Use a wide-angle lens if you want to get the whole tower from the base.
The age of the clock is more than just a number on a calendar. It represents the height of the Industrial Revolution and the moment London decided to tell the world exactly what time it was. It’s been through a lot. A few cracks and a slight lean just give it more character.
Next time you hear that chime, remember you’re listening to a 13-ton piece of Victorian metal that’s been vibrating for over a century and a half. It’s a miracle it hasn't fallen apart.
To see the current schedule for chimes or potential maintenance pauses, check the official UK Parliament heritage site before your trip to ensure you actually get to hear the Great Bell in person.
