The Galleria d'Arte Moderna di Genova, also known as GAM, owes the initial core collection of its collection to Prince Odone of Savoy and subsequent bequests and acquisition campaigns.

The Galleria d'Arte Moderna is located in the sixteenth-century Villa Saluzzo di Nervi and houses over 2,500 works including paintings, sculptures, drawings, and engravings dating from the early nineteenth century to the present day.

Among the numerous artists represented here are: Nicolò Barabino, Ernesto Rayper, Alfredo D'Andrade, Vincenzo Cabianca, Plinio Nomellini, Rubaldo Merello, Fortunato Depero, Felice Casorati, Filippo De Pisis, Francesco Messina, Eugenio Baroni, Arturo Martini, Renato Guttuso, Mario Mafai, Corrado Cagli. The GAM also boasts the most extensive public selection for en plein-air painting of the Scuola dei Grigi.

Here you can find works by Tammar Luxoro, Alfredo D'Andrade, and Ernesto Rayper; one of the most extensive selections of divisionist works by Rubaldo Merello and two famous and imposing canvases by Plinio Nomellini.

Within the remarkable cultural context is the gypsum collection of the great sculptor Giulio Monteverde: here are gathered over fifty sculptures, and in the room dedicated to the work of Arturo Martini, is preserved at life size, La Convalescente, a wonderful terracotta work. Among the foreign artists documented in the collections are some of the significant figures of the international post-impressionism including the American Richard Miller and the Parisian artist Lucien Simon.
