St. Patrick’s Cathedral and Christ’s Church Cathedral in Dublin Ireland.
These two Cathedrals, once Catholic Cathedrals of Dublin, were stolen while Elizabeth I was attempting to convert Ireland to the Anglican church. Her attempts failed at the time and the Irish people remained Catholic, however, she was able to take the two Cathedrals and turn them into Anglican churches. To this day they are no longer Catholic Cathedrals, but the church recognizes them as stolen property, and so they have not built a new Cathedral in Dublin because of this. So although there are countless Catholic churches in the city, there is still no main cathedral.
