During the twentieth century the Museum Revoltella continued to grow, becoming an increasingly prestigious cultural institution and an important reference for modern and contemporary art, presenting all the important names of 20th century Italian art, including Casorati, Sironi, Carrà, Mattes, Bolaffio, Morandi, De Chirico, Manzù, Marini, Fontana and Burri. It has also staged notable exhibitions that have made significant scientific contributions to the knowledge of the art of the past two centuries.
In the 60s the museum expanded further by acquiring the nearby Palazzo Brunner where, after a long renovation - begun in 1968 by Carlo Scarpa and finished in 1991 - new exhibition spaces were obtained for the gallery of modern art.
