The Houses of Parliament and Elizabeth Tower, commonly called Big Ben, are among London’s most iconic landmarks and must-see London attractions. Technically, Big Ben is the name given to the massive bell inside the clock tower, which weighs more than 13 tons (13,760 kg).

The name Big Ben is often used to describe the tower, the clock and the bell but the name was first given to the Great Bell.
The Elizabeth Tower, which stands at the north end of the Houses of Parliament, was completed in 1859 and the Great Clock started on 31 May, with the Great Bell strikes heard for the first time on 11 July and the quarter bells first chimed on 7 September.
