Salzburg's Cathedral is probably the city's most significant piece of church architecture and its ecclesiastical centre. With its magnificent façade and mighty dome it represents the most impressive early Baroque edifice north of the Alps. Destroyed by fire and rebuilt, enlarged and expanded, it bears witness to the power and independence of Salzburg's archbishops. Among the precious objects to be found in Salzburg's Cathedral are the baptismal font in which Wolfgang Amadeus Mozart was baptised, the majestic main organ, surrounded by angels playing instruments and crowned by Rupert and Virgil, as well as the magnificent Cathedral portals made by Scheider-Manzell, Mataré and Manzú. In his capacity as the court organist and concert master, Wolfgang Amadeus Mozart composed numerous undying works of sacred music for Salzburg.
