Antoniuskirche, Graz, Baroque church in Innere Stadt, Graz, Austria

The Antoniuskirche is a Roman Catholic church on the eastern slope of the Schlossberg, next to the Styrian Folklore Museum in Paulustorgasse. Its plain exterior shows only a staircase and a gable facade with a round window. Inside, the single-nave nave has three bays under a barrel vault, with a Baroque high altar whose altarpiece was painted by Giovanni Pietro de Pomis in 1602.

The church belongs to the first Capuchin settlement in Styria, built 1600–1602. On 8 August 1600, 10,000 Protestant books and writings were burned on the site, the closing act of the expulsion of Protestants from Graz; two days later the papal nuncio erected a wooden cross and laid the foundation stone. The monastery was dissolved in 1786 under the Josephine reforms and used as a psychiatric institution until the Folklore Museum moved in in 1913.

The high altarpiece was painted in 1602 by Giovanni Pietro de Pomis, court artist and architect of Graz's Mausoleum, and shows the Counter-Reformation triumph with a plea for blessing on the monastery foundation. A second de Pomis painting, made for the former Poor Clares' church, shows Archduchess Maria with the Christ Child raising a hand in blessing over her.

The church is not inside the Styrian Folklore Museum; it stands next to it on the eastern slope of the Schlossberg, reached via the Paulustorgasse. From outside, look for the stairway and the plain gable facade with a round window, since the building is otherwise easy to miss. The interior is a single nave of three bays.

The high altarpiece was painted in 1602 by Giovanni Pietro de Pomis, court artist and architect of Graz's Mausoleum and Katharinenkirche. It glorifies the Counter-Reformation and asks a blessing on the monastery's founding. A second de Pomis painting, made for the no longer existing Clarissen church, shows Archduchess Maria with the Christ Child raising a hand in blessing over her.
