Which Irish city has two cathedrals, St Fin Barre's and St Mary's?

Dublin - even more famously- has 3. The 2 original historic Catholic cathedrals, which were seized in Tudor times and are still in the possession of the Church of Ireland. (i.e. Irish Anglicans.) Despite the microscopic size of their congregations they doggedly refused to return either one.. Third is the Catholic pro-cathedral, a large Victorian type church.
