A bell foundry is a specialized workshop where bells are cast and manufactured. The process involves melting metal, usually bronze, and pouring it into molds to create bells of various sizes and tones. Bell foundries have a long history, dating back to ancient times, and they often produce bells for churches, schools, and public buildings. In addition to casting bells, a bell foundry may also provide tuning and restoration services. Famous bell foundries, such as the Whitechapel Bell Foundry in London, have produced iconic bells, including the Big Ben bell. These foundries play a crucial role in preserving the art of bell-making.
