Big Ben, the bell tower of the British Parliament Building (Westminster Palace), built in 1859 on the banks of the Thames in London, is one of London's famous ancient bells and landmarks. The bell tower is 95 meters high, the bell diameter is 9 feet, and the weight is13.5 tons. It has been more than a century since Big Ben began to report for London in 1859. Big Ben is also an important place for British people to celebrate the New Year. It is not open to non-British people. But when you visit the Congressional Chamber, you can get close to Big Ben, free of charge and no reservation.
