The most famous clock tower in England is the Elizabeth Tower, commonly known as Big Ben, located at the north end of the Palace of Westminster in London. Although "Big Ben" originally referred to the Great Bell housed within the tower, the name has become synonymous with both the bell and the clock tower itself. Completed in 1859, the tower has become an iconic symbol of London and British heritage. Its remarkable clock mechanism ensures accurate timekeeping, and its distinctive Gothic Revival architecture attracts millions of visitors each year. Big Ben's bells also play an essential role in public life, marking the hours and significant occasions.
