A baptistery is a building or designated area used for the Christian rite of baptism. It is often located near a church and is specifically designed for the ceremonial immersion or sprinkling of water on individuals, symbolizing their initiation into the Christian faith. Baptisteries can vary in size and architectural style, ranging from simple structures to elaborate designs featuring intricate artwork. Historically, baptisteries were significant in early Christianity, with many famous examples, such as the Baptistery of St. John in Florence and the Neonian Baptistery in Ravenna. These structures often include a baptismal font, where the actual baptism takes place, and may also serve as a place for reflection and prayer.
