How did Johann Bernhard Fischer von Erlach change the appearance of Salzburg?

Johann Bernhard Fischer von Erlach significantly transformed the appearance of Salzburg through his work as an architect for Archbishop Johann Ernst, Count von Thun. His contributions to church architecture and town planning fundamentally altered the city's skyline and urban character.1

Key changes to Salzburg included:

• Dominant Landmarks: He introduced new domes and towers that reshaped the city's overall appearance. Notably, the Kollegienkirche (University Church) provided a new architectural and symbolic accent, with its geometric forms and undulating towers crowning the university complex.12
• Dynamic Facades: His churches, such as the Dreifaltigkeitskirche (Church of the Holy Trinity), featured elegant, two-towered facades accented by dynamic curves. The concave facade of the Dreifaltigkeitskirche was specifically designed to contrast with and heighten the effect of the adjoining seminary buildings.1
• Urban and Secular Projects: Beyond ecclesiastical structures, he redesigned the archbishop’s stables, laid out the square in front of them, and converted an old quarry into a summer riding school. He also designed the archbishop’s summer residence, Schloss Klesheim, located outside the city.1
