The Palazzo Giustino Quadrari, situated in the historic centre of San Donato Val di Comino, is an elegant 18th-century building in the Vanvitellian style, constructed by local stonemasons. Named after Giustino Quadrari, a distinguished 19th-century scholar, the palace bears traces of his erudition and his connections with the Bourbon court of Ferdinand II. Quadrari, an expert in sacred archaeology, papyrology and palaeography, was the scholar who deciphered the famous “Herculaneum papyri”. After the unification of Italy, he returned to his hometown and helped restore his family home, situated in Piazza Tolosa, now renamed Piazza Giustino Quadrari.
The square is home to Palazzo Giustino Quadrari, where visitors can admire Roman-era inscriptions discovered in the San Donato area. Its historical significance is further highlighted by the fact that, in 1876, the historian Mommsen recorded them in his *Catalogue of Latin Inscriptions*. The square, formerly known as Piazza Tolosa, was named after Giustino Quadrari two years after his death, in 1871, as a tribute to him as an intellectual and man of culture.
