The Houses of Parliament's iconic clock tower is one of London's most famous landmarks!
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 clock tower looks spectacular at night when the four clock faces are illuminated.
Elizabeth Tower stands at more than 96 metres tall, with 334 steps to climb up to the belfry and 399 steps to the Ayrton Light at the very top of the tower.
It is not possible for overseas visitors to tour the clock tower. Instead, join a talk on the Elizabeth Tower or take a tour of the Houses of Parliament next to The Elizabeth Tower. Alternatively, watch this behind-the-scenes video of Big Ben in action.
