With about 3,000 square metres of exhibition space the Museum der Moderne Salzburg presents year-round national and international exhibition projects in its two museums from the classical modern to current art since the end of the 2nd World War to contemporary art. The collection policy focuses on internationalisation with a vision based on content.

The Museum der Moderne Salzburg used to consist only of the Rupertinum Art Museum between the Franziskanerkirche and the Festival Halls, but recently it was extended and now occupies a new site on the Mönchsberg. It is dedicated to pot-war and contemporary art.

The "Rupertinum" is the older sister of the Museum der Moderne Salzburg. As the MMS, it is owned by the federal province of Salzburg. Since 1983, it occupies a Baroque townhouse in the heart of the city, to the opposite of the Franziskanerkirche. It focuses on graphics, but changing exhibitions tend to have themes from a variety of different art forms.
