A church bell is a bell which is rung in a (especially Christian) church either to signify the hour or the time for worshippers to go to church, perhaps to attend a wedding, funeral, or other service. Before mass communication they were the only way to gather a village together, so they served for secular functions also. European Christian church bells typically have the form of a cup-shaped cast metal resonator with a flared thickened rim, and a pivoted metal striker or clapper hanging from its center inside. It is usually mounted high in a bell tower on top of the church, so it can be heard by the surrounding community. The bell is suspended at its apex from a horizontal axle, so it can swing from side to side. A rope is tied to a pulley or lever on the axle, and hangs down to ground level. To ring the bell, the bell-ringer pulls on the rope, swinging the bell. The motion causes the clapper to hit the inside rim of the bell as it swings, making the sound. Alternatively, the bell may be suspended from a stationary support, and the bell rung by pulling a rope attached to the clapper to one side.
