When Archbishop John Thomas Troy's committee bought Lord Annesley's townhouse on Marlborough Street in 1803, the plan was always to build something grander, somewhere more prominent, as soon as the law and the money allowed. The replacement never came. The 'pro-cathedral' - the provisional cathedral - opened in 1825 on a back street that never quite became a front one, and served as Dublin's de facto Catholic cathedral for exactly two hundred years. Then, in November 2025, Pope Leo XIV quietly designated St Mary's the official Catholic Cathedral of Dublin - the first the city had possessed since the Reformation closed the medieval ones five centuries earlier.
