Baptristy

"the ancient Christian discipline has not entirely disappeared, and it is interesting to observe how, in many places, certain ceremonies are reserved to the cathedral, especially the administration of baptism. In Florence, Sienna, Pisa, and other cities, the parish churches have no baptismal fonts, and all children, unless in urgent cases, must be baptized in the cathedral, or, rather, in the baptistery." (per the Catholic Encyclopedia).
