Klagenfurt Cathedral was built in 1581 as a Protestant prayer house, making it the largest Protestant church built in Austria. Closed in 1600 during the Counter-Reformation, it was handed over four years later to the Jesuits who occupied it until the dissolution of the order in 1773. In 1787, the church was elevated to the rank of a cathedral.
