The Jesuitenkirche (Jesuit Church), also known as the Universitätskirche (University Church) is an ornate church in Vienna, Austria on Dr. Ignaz Seipel-Platz, immediately adjacent to the old University of Vienna buildings.
The Jesuitenkirche was built between 1623 and 1627 on the site of an earlier chapel, at the time when the Jesuits merged their own college with the University of Vienna's philosophy and theology faculty. The Emperor broke ground for both college and church, with the church itself dedicated to Saints Ignatius Loyola and Francis Xavier. In 1703, Brother Andrea Pozzo, SJ, added twin towers and reworked the facade in baroque style. The church was then rededicated to dedicated to the Assumption of Mary. Despite its relatively austere exterior, the interior is remarkably opulent with ersatz marble pillars, gilding, a number of allegorical frescoes, and remarkable trompe-l'oeuil ceiling domes. Immediately adjacent is the Aula, where Haydn's oratorio The Creation had its premiere, as did Beethoven's Seventh Symphony.
