The clock tower in London is commonly known as Big Ben. However, it’s important to note that Big Ben actually refers to the Great Bell inside the tower, rather than the tower itself. The official name of the tower is the Elizabeth Tower, renamed in 2012 to honor Queen Elizabeth II's Diamond Jubilee. The tower is an iconic symbol of London and a significant landmark, often visited by tourists and used in various media representations of the city. Big Ben has become synonymous with London and serves as a reminder of British history and culture.
