The Catholic faith was brought by Spanish colonists and gradually became the dominant religion in Puerto Rico. The first dioceses in the Americas, including that of Puerto Rico, were authorized by Pope Julius II in 1511. In 1512, priests were established for the parochial churches. By 1759, there was a priest for each church. One Pope, John Paul II, visited Puerto Rico in October 1984. All municipalities in Puerto Rico have at least one Catholic church, most of which are located at the town center, or plaza.
