A prestigious exhibition space is housed in the old medieval buildings in Rimini historic center, the thirteenth-century Palazzo dell'Arengo and the fourteenth-century Palazzo del Podestà, which together with Palazzo Garampi, the Galli Theater and the Pescheria overlook Piazza Cavour, the heart of the city. 

Here the ancient heritage is the exhibition space of the medieval palaces, in the heart of the historic center, restored to their original splendor by a project of restoration and architectural enhancement. And the contemporary is its contents, which until 2023 consisted of the eclectic and varied collection of important 20th-century works donated by established contemporary artists from the Italian and international scene to theFondazione San Patrignano.
Following redevelopment work (2023 – 2025) to ensure full accessibility to all exhibition and auxiliary spaces, the Palazzi dell'Arte have reopened to the public. Since mid-September 2025, they have reached total accessibility across all areas and now host contemporary art exhibitions and displays.

On the rear of the two medieval buildings there is the Sculpture Garden which fades into the museum's exterior. This garden, set up on a project by Luca Cipelletti, creates a path to be experienced both as a museum space and as an Italian garden where you can stop and relax. Today, the garden showcases works by Piotr Uklanski, Kiki Smith, Arnaldo Pomodoro, Giuseppe Penone, Paul Kneale, and Alberto Garutti. These can be admired either as an additional part of the museum tour or by those simply wishing to stroll through the grounds (free entry).
Late opening: during the summer, the gardens remain open every Wednesday and Friday evening, coinciding with the museums' late-night openings (July and August, from 9 pm to 11 pm).
