A baptistery is a building or designated area within a church where the sacrament of baptism is performed. It is often separate from the main worship space to emphasize the significance of the baptismal rite. Baptisteries can be found in various architectural styles and are typically adorned with religious art, such as mosaics or sculptures, that depict biblical themes. In many Christian traditions, the baptistery contains a baptismal font, which is a basin or pool used for the baptismal ceremony. The design and location of the baptistery can vary widely, with some famous examples being the Baptistery of Florence in Italy and the Baptistery of St. John in Rome.
