The Cathedral of the Blessed Sacrament, sometimes referred to as the Christchurch Basilica or the Catholic Cathedral, was a Catholic cathedral on Barbadoes Street in central Christchurch, New Zealand. It was the mother church of the Roman Catholic Diocese of Christchurch and seat of the Bishop of Christchurch. It was not a basilica, despite sometimes being referred to as one: the term was used because its design was similar to some European basilicas.
