Since its founding in 1973, Galleria 13 has always worked to promote art, consolidating collaborative relationships with public and private institutions, associations, and art galleries throughout Italy. It has promoted the dissemination of modern artists such as Antonio Ligabue, Franco Rognoni, Alberto Manfredi, and Enrico Paulucci, whose interests the Gallery represented for many years; and it discovered the contemporary painter Carla Bedini. It maintains ongoing collaborations with a careful selection of contemporary painters, including Davide Benati, Massimo Pedrazzi, Alessio Vaccari, Omar Galliani, Jonathan Guaitamacchi, Enrico Ingenito, and Franco Chiarani.

In 2011, under the careful guidance of the new Art Director Sara Cavagnari, Galleria 13 decided to open up to Fine Art Photography by presenting a limited and carefully selected group of international photographers. Galleria 13 currently represents in Italy the Anglo-American photographer Michael Kenna, one of the most popular landscape photographers of our time; the controversial Japanese artist Nobuyoshi Araki; the street photographer Daido Moriyama; Kenro Izu; and the new promise of Japanese photography Kazuaki Koseki.

Among the Italian photographers represented by the Gallery are Maurizio Galimberti, Bruno Cattani, Luigi Ghirri, Franco Fontana, and Vasco Ascolini.

Since 2015, Galleria 13 has been the official representative of Michael Kenna in Italy for the sale of his photographs, the temporary loan of public exhibitions, and the permanent archive.

There is also a very close direct collaboration with the archive of Nobuyoshi Araki, which, through Galleria 13, brings prominence to the works of this eclectic artist in Italy and abroad.
