Tsar Kolokol

Throughout the centuries, bell founders have always been amongst the most skilled metal technologists, as is demonstrated by Tsar Kolokol, at 195 tonnes the largest bell in the world, which was cast in Moscow in 1735. Unfortunately it was damaged by a fire in 1737 before it could be hung. Since then it has stood on a platform in the Kremlin. The fragment that broke away weighs about 11 tonnes!
