Dominican Church, Early baroque church in Innere Stadt, Austria

The Dominican Church is a baroque house of worship in Vienna's old town featuring an octagonal dome and a Roman baroque facade. The interior space is defined by these architectural elements and displays the characteristic style of the period.

Emperor Ferdinand II commissioned Italian architect Jacopo Tencala to design this church in 1631, and it has shaped the area ever since. The building rose during a period of major transformation in Vienna's urban landscape.

The church is known as the Rosary Basilica, a title Pope Pius XI granted in 1927. Its dedication to Our Lady of the Rosary appears in the ceiling frescoes by Matthias Rauchmiller (1675), whose 46 scenes depict the life of Mary, and in Carpoforo Tencalla's paintings of the Battle of Muret (1213) and the Battle of Lepanto (1571), victories attributed to the rosary.

The church stands at Postgasse 4 on the Dominikanerbastei in the 1st district, not on Salzstrasse. Enter from Postgasse; the nave, six side chapels and transept are on one level, with steps up to the gallery and organ loft. A thorough renovation ran from 2020 to 2022, so some furnishings and the choir were reworked.

The high altar's centrepiece is a 720 by 430 cm canvas by Leopold Kupelwieser, painted in 1840, showing Pope Pius V instituting the Feast of the Rosary. The gilded brass tabernacle in front of it dates from 1885. The red-marbled wooden retable by Carl Roesner replaced the old altarpiece in 1839–1840.
