A baptistry is a special area or building used for the Christian ritual of baptism, which symbolizes a person's initiation into the faith. It often contains a large basin or pool filled with water, where individuals are immersed or sprinkled with water as part of the ceremony. Baptistries can be found in churches or as standalone structures, and they may be designed in various architectural styles. Historically, baptistries have been significant in many Christian traditions, including Catholicism, Orthodoxy, and Protestantism. They serve not only as functional spaces for baptism but also as places of reflection and spiritual significance. Some famous examples include the Baptistery of St. John in Florence and the Baptistery of Neon in Ravenna.
