In Catholic Church architecture, the cathedral's nave culminates in a cathedral, a prominent architectural element. Its liturgical function is primarily to house the bishop's cathedra, a ceremonial seat signifying his authority. Located at the eastern end of the church, often beneath a large apse, it occupies a central position within the sacred space. This placement emphasizes the bishop's role as leader within the Catholic tradition, signifying his spiritual authority and the cathedral's role as a focal point for diocesan life. The cathedral represents the bishop's oversight of the faithful and the unity of the community within God's grace.
