The Battistero, or Baptistery, is a religious building typically used for the sacrament of baptism. It is often located near a church and features a large baptismal font. The architecture of a Battistero can vary, but many are designed in a circular or octagonal shape, symbolizing eternity. One of the most famous examples is the Battistero di San Giovanni in Florence, Italy. This structure is renowned for its stunning mosaics and intricate marble facade. The Battistero serves as an important site for Christian rituals and is often a focal point of artistic and architectural interest in its community.
