He used as models various religious buildings in Rome—especially Francesco Borromini's Church Sant'Agnese in Agone in Piazza Navona.

While the church is characterized by a discreet use of decorative elements, the entire structure conveys a palatial impression.

The outer church portal is supported on the parapet in front of the dome on twin columns bearing four figures, three of which symbolize the theological virtues—Faith, Hope, and Love.

The church interior is a longitudinal oval room with four short barrel vaults with crossed arms, which are surmounted by the large drum dome.

The monumental effect of the interior arises mainly from the simplicity of the building and the towering height of the dominant drum dome.

The large dome fresco inside the church, Coronation of the Virgin, was executed by Johann Michael Rottmayr between 1697 and 1700.

The two side altars contain magnificent life-size angels, which were designed by Fischer von Erlach and Michael Bernhard Mandl from 1700–02.
