The art of bellfounding reached its pinnacle in the 18th century, with the production of unimaginably huge bells. The largest bell in the world, the Tsar Bell (218 tons) was cast in 1733 for the Ivan the Great Bell Tower in Moscow. Unfortunately, the Tsar Bell was damaged in a fire in 1737 before it could be successfully hung, and stands today at the base of the tower. The largest working bell in the world is the Dormition Bell (144,000 lb) which hangs in the same Ivan the Great Bell Tower.
