A Roman Catholic Archdiocese is a significant ecclesiastical jurisdiction in the Roman Catholic Church, led by an archbishop. It typically encompasses a large geographical area and includes several smaller dioceses, which are overseen by bishops. The archdiocese serves as a central hub for the church's activities, administration, and spiritual guidance within its territory. The archdiocese plays a vital role in the church's mission, including the celebration of sacraments, education, and community outreach. It is part of a larger structure that includes the Vatican, the Pope, and various other dioceses, all working together to promote the teachings of Catholicism.
