An Archdiocese is a significant ecclesiastical jurisdiction in the Roman Catholic Church, typically overseeing a group of smaller dioceses. It is led by an Archbishop, who has authority over the bishops in the region. The archdiocese serves as a central point for administrative, pastoral, and liturgical activities within its territory. Archdioceses are often located in major cities and play a crucial role in the Church's mission, including education, charity, and community services. They are part of a larger structure that includes the Vatican and various other dioceses, contributing to the global Catholic community.
