The Tsar Bell stands beside the bell tower. It is the world's biggest bell, weighhing 202 tonnes, but it has never rung. An earlier version, weighing 130 tonnes, fell down and shattered during a fire in 1701. This new one was cast in the 1730s for Empress Anna Ivanovna. It was cooling of in the foundry casting pit in 1737 when it came into contact with waster, causing an 11-tonne chunk to chip off. More than 100 years later the damaged bell was placed beside the bell tower.
