The new-found self-awareness of the Counter-Reformation didn’t allow any more such a sorry state for a church. In 1631 the Dominicans started to build a new oblong church with a dome, following the plan of Jacopo Tencala, architect of Prince Maximilian of Liechtenstein. The master builders were Jacopo Spacio, Cipriano Biasino and Antonio Canevale. They introduced to Vienna the Baroque style of Italy. The first stone was laid by emperor Ferdinand II on 29 May 1631. The structural work was finished in 1634. The church was consecrated on 1 October 1634. The finishing touch was finally given in 1674. The church was elevated to the status of basilica minor in 1927 under the name “Rosary Basilica ad S. Mariam Rotundam”.
