The Museum der Moderne Salzburg has the use of two buildings with spacious galleries on altogether six floors. The Rupertinum, an early-Baroque-era structure in the heart of Salzburg’s old town, was inaugurated in 1983, followed by the second venue atop Mönchsberg hill in 2004. The Rupertinum houses the Generali Foundation Study Center and the libraries of the Generali Foundation and the Museum der Moderne Salzburg.
The former water tower on the Mönchsberg was redeveloped for the museum and now contains offices, workshop spaces, and a studio apartment for an artist; it was named Amalie Redlich Tower and taken into service in 2014. In 2017, the museum opened a new art storage space in Guggenthal (municipality of Koppl) outside Salzburg.
