The Italian Catholic Church, or Catholic Church in Italy, is part of the worldwide Catholic Church in communion with the Pope in Rome, under the Conference of Italian Bishops. The pope also serves as Primate of Italy and Bishop of Rome. In addition to the Italian Republic, two other sovereign states are included in Italian dioceses: San Marino and Vatican City. There are 225 dioceses in the Catholic Church in Italy; see further in this article and in the article List of Catholic dioceses in Italy.
The pope resides in Vatican City, enclaved in Rome. Having been a major centre for Christian pilgrimage since the Roman Empire, Rome is commonly regarded as the "home" of the Catholic Church, since it is where Saint Peter settled, ministered, served as bishop, and died. His relics are located in Rome along with Saint Paul's, among many other saints of Early Christianity.
