A "Tower Bell" is a large bell typically housed in a tower, often found in churches, clock towers, or public buildings. These bells are designed to produce a loud, resonant sound that can be heard from a distance. They are commonly used to signal the time, mark special occasions, or call people to worship. Tower bells are usually made of bronze and can vary in size and weight. The mechanism for ringing the bell can be manual, using ropes, or automated with a system that strikes the bell at set intervals. Famous examples include the Liberty Bell and the Big Ben bell in the Elizabeth Tower.
