The body of the church is made of dark grey stone with ornamentation and façade of bright Untersberg marble. The richly decorated façade is framed by two towers and topped by a curved gable. The north tower houses an old oven used for baking communion bread. The façade is divided into three horizontal sections. The lower section has three high round arches or portals that provide access to three bronze doors. The portals are flanked by four large sculpted figures representing the diocesean and cathedral patrons. Mitred figures of Saint Rupert holding a salt barrel and Saint Virgilius holding a church were created c. 1660 by Bartholomäus van Opstal and flank figures of Saint Peter holding keys and Saint Paul holding a sword, sculpted c. 1697 by Bernhard Michael Mandl, who also created all the pedestals. The bases bear the arms of the Prince Archbishop Guidobald von Thun and Prince Archbishop Johann Ernst von Thun.
