In Catholic tradition, a co-cathedral serves as a secondary cathedral within a diocese. Its liturgical function mirrors that of the principal cathedral, offering the full range of sacred rites and ceremonies. This architectural element usually occupies a significant position within the diocese, often in a large city or town geographically distant from the main cathedral. Its presence ensures easier access to the sacred space for a wider population. The co-cathedral holds the same symbolic meaning as a cathedral, representing the bishop's authority and the central focus of Catholic worship within its designated area.
