The inside of the church is made almost entirely of white stucco, giving it a very bright appearance and setting it apart from most other Munich churches. German sculptor Wolfgang Leutner was responsible for creating the statues while Italian Nicolo Petri designed the stucco decorations for the interior. Numerous paintings by Caspar de Crayer, Carlo Cignani, George Desmarées and Joachim Sandrart can be found inside around the great black altar, which was designed by Andreas Faistenberger.
