Established in 1958 by the restorer and antiquarian Pino Marletta, whose passion passed through is son Alessandro, the Gallery lies at the core of Florentine arts and antiquities, inside the renaissance Ridolfi Guidi Palace, which hosted the English poets Elizabeth Barrett Browning and Robert Browning in the 19th century.

It is specialised  primarily in Italian drawings, paintings, sculptures and works of art from the 16th to the 20th century; its main goal is the search for quality and uniqueness of the items, obtaining the esteem and interest of important national and international institutions, as well as connoisseurs and private collectors. It promotes both thematic (“Metamorphosis of the Nude” curated by prof. Carlo Sisi in 2019 and “Fascination and elegance in neoclassical art” curated by prof. Sandro Bellesi in 2022) and monographic (“Drafts, drawings and sketches. Behind the scenes of Giovanni Colacicchi’s art” in 2022) exhibitions.
