The original 17 Russian bells from the Danilov Monastery in Moscow were purchased in 1930 by Charles Crane, a patron of Russian Orthodox Art. This unique set of bells was subsequently donated to Harvard. In 2008, a bell exchange was concluded through which the original bells were returned to Russia and replicas were specially cast for Harvard at Voronezh. The bell in this photograph is called Mother Earth and weighs nearly 13 tons.
