@meipath: The Tsar Bell in Moscow: the biggest bell on Earth, and it has never rung. The Tsar Bell was cast in 1735 and was still in its casting pit when a fire reached it in 1737: cold water hit the hot bronze and an 11.5-ton slab broke off. It sat in the pit 99 years, until a rig pulled it out in 42 minutes 30 seconds in 1836.
