The first church on this site was built in 1237 by the newly arrived Dominicans on a parcel of land allotted in 1225-1226 by the duke Leopold VI.

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.

Above the portal one can see the statues of St. Catherine of Siena and Agnes of Montepulciano, kneeling at the feet of Our Lady, patron saint of this church.

The ceiling frescoes are the work of Matthias Rauchmiller (1675), showing in their color and composition the influence of Peter Paul Rubens.

The medallions in the four supporting columns are by an unknown artist, depicting three popes from the Dominican Order (Innocent V, Benedict XI and Pius V) and St. Antony of Florence.

The large statues in these columns show us the four original Doctors of the Church (Jerome, Gregory the Great, Augustine and Ambrose), all sculpted by a local artist.

The apse is dominated by the imposing red-marbled wooden retable in Baroque style from 1839-1840 by Carl Roesner, replacing the dilapidated old altarpiece.

The antependium shows a blue globe surrounded by a rosary and below, in the medaillon, the motto "toto diffunditur orbe" (spread all over the world).

On the canopy of the pulpit the Holy Spirit, represented in the form of a dove, is surrounded by a halo of light and angels in elegant poses.

The painting under the rood loft is by an anonymous master from 1642 and depicts the glorification of the rosary and the mediation via Saint Dominic.
