Big Ben is probably the world's most famous clock. That iconic silhouette is instantly recognisable and is one of the most Instagrammed landmarks on the planet. Six monarchs and 41 prime ministers have come and gone since the bells first struck their now familiar music across Westminster.

Big Ben—which is technically the name of the Great Bell inside the Elizabeth Tower—is famous as a global icon of London, British resilience, and the "mother of parliaments." Completed in 1859, it was the largest and most accurate four-faced striking and chiming clock in the world at the time, representing the pinnacle of Victorian engineering. Its distinctive "E-natural" chime is recognized worldwide, famously broadcasting live over the BBC during World War II, where it became a symbol of hope and punctuality amidst the Blitz. Architecturally, the tower’s Neo-Gothic design by Augustus Pugin is a masterpiece of the Palace of Westminster, which is a UNESCO World Heritage site. Beyond its physical grandeur, Big Ben has been immortalized in countless films, books, and artworks as the "establishing shot" for London, cementing its status as a visual shorthand for the United Kingdom. Its reliability—adjusted by adding or removing pre-decimal pennies from the pendulum—makes it a living monument to tradition and the enduring nature of democratic government, drawing millions of visitors each year to witness the heartbeat of the British capital.
