The Tsar Kolokol (Tsar Bell) at the Kremlin in Moscow is the largest bell in the world, weighing approximately 201 tons. It was cast in 1735 and remains in the Kremlin grounds. The bell in Rome is St. Peter's, but smaller. There is no famous bell at St. Francisco church in California that holds this record, and Goa's churches don't have the world's largest bell.
