A belfry is a structure or part of a building that houses one or more bells. Often found in churches, towers, or clock towers, belfries are designed to allow the sound of the bells to be heard over a wide area. The bells are typically rung to signal the time, mark special occasions, or call people to worship. In addition to their functional purpose, belfries can also be architectural features that enhance the beauty of a building. Many belfries are designed in various styles, reflecting the culture and history of the region, and can be seen in famous structures like the Big Ben in London or the Campanile in Venice.
