The famous British clock tower is known as Big Ben, although technically, this name refers to the Great Bell within the tower. Big Ben is part of the Palace of Westminster in London and has become an iconic symbol of the city. The tower was renamed Elizabeth Tower in 2012 in honor of Queen Elizabeth II's Diamond Jubilee, but many still refer to it as Big Ben. The clock tower was completed in 1859 and features intricate Gothic architecture. With its impressive clock faces and striking chimes, Big Ben is a beloved landmark visited by millions each year.
