The Salzburg Baroque Museum was installed in the southern wing of the former Orangery in 1973. The works of art on display are first-rate examples of progressive sketches and designs of monumental structures in the 17th and 18th centuries. The collection was donated to the City and Province of Salzburg by Professor Dr. Kurt Rossacher and his wife Else under the proviso that the collection be open to the public. The exhibits range from works by Rubens, Cortona, Maffei, Bernini and Algardi, Rottmayr, Altomonte and Troger, Tiepolo and the Guardis to Maulbertsch and Fragonard.
