The bell, which weighs a symbolic 9,801 kilograms, was cast in Innsbruck, Austria, by the Grassmayr Bell Foundry, which has been in operation since 1599. Petr Grassmayr, the current owner, said the bell was a symbol of peace, 80 years after bells were destroyed for war. He called on people to remain vigilant in maintaining peace, as that is the most important thing we have.
