Yes, Big Ben (officially the Great Bell within the Elizabeth Tower) is fully operational in 2026 and remains the most iconic timekeeper in the world. Following its massive five-year restoration completed in 2022, the Great Clock’s Victorian mechanism is now more accurate than ever. It continues to strike the hour with its famous "bongs," and the four smaller quarter bells chime the Westminster Quarters every 15 minutes. The clock’s four faces are illuminated from within by new, energy-efficient LED lights that can change color for special national events. Beyond its physical function, the bell’s strikes are broadcast live on BBC Radio 4 several times a day, maintaining its role as a vital national pulse. In 2026, visitors can also take guided tours to the top of the tower to see the mechanism and the bell up close, though these tours must be booked months in advance due to their extreme popularity.
