Almost entirely dedicated to paintings, the upper loggia gathers some of the most important and precious works of the Republic.

Among these, particularly interesting are two altar-pieces by Girolamo Marchesi from Cotignola (Ravenna, 1472 approx. – Rome, 1540 approx.) representing the Conception with Saints Augustine and Anselmo (1512) and the Virgin on her Throne and Saints (1540).

The first panel painting, ordered by the friars for the Conception Altar, is a masterpiece of the artist’s production and one of the most ancient portrays of Mount Titano. The other panel painting, the second work ordered by the friars to Girolamo Marchesi from Cotignola, is one of the first and most effective representations of Saint Marino. Here, the Saint is ideally portrayed with Mount Titano in his hands, thus “protecting” his town.  

Particularly precious are also two small panel paintings on gold background, attributed to Niccolò di Liberatore called “l’Alunno” (1430 approx. – 1502), both representing a couple of Franciscan saints, that is Saint Bonaventura and Saint Anthony of Padua and Pope Nicolò IV and Saint Francis respectively.

Of exquisite manufacture is also the great 15th-century panel painting representing St. Anthony Abbot among the Saints Anthony of Padua and Agata by Timoteo Viti from Urbino, Raphael’s master, in the Perugian style. This altar-piece, originally located above one of the altars of the conventual church, shows one of the most ancient images of Saint Agata, who became joint patron saint of the Republic in 1740.

Among the ancient furnishings of the convent is a rare chest-coffer dating back to the first 25 years of the 17th century. The real function of this solid and very simple chest can be inferred from its locking system. Indeed, besides the missing frontal bolts, its ingenious lock could only be opened by using, at the same time, three keys once given to three different religious men.
