The famous clock in London is known as Big Ben, although this name actually refers to the Great Bell inside the clock tower at the north end of the Palace of Westminster. The tower itself was renamed the Elizabeth Tower in 2012, in honor of Queen Elizabeth II's Diamond Jubilee. Completed in 1859, Big Ben is renowned for its striking presence and accuracy. The clock has become an iconic symbol of London, featuring prominently in various cultural depictions, and is a significant tourist attraction.
