A belfry is a structure or part of a building that houses one or more bells. Often found in churches or towers, belfries are designed to allow the sound of the bells to be heard over long distances. The bells are typically rung to signal the time, mark special occasions, or call people to worship. Belfries can vary in design, from simple wooden frames to elaborate stone towers. In addition to their functional purpose, they often serve as architectural features that enhance the beauty of a building, such as a church or town hall.
