Founded in 1977 and housed in the monastic complex of San Benedetto Po, founded by Tedaldo di Canossa in 1007, the Museo Civico Polironiano, with over 13,000 objects, offers material and immaterial testimonies of the river plain crossed by the Po, between the Prealps and the Tuscan-Emilian Apennines. It includes sections dedicated to material culture and rural society, magic, popular religion, local legends, and artistic expressions of the Padan world. Also of notable interest is the collection of Reggio-Modena agricultural carts and the historical-archaeological collection, exhibited in the basement of the former monastery refectory. Special mention is deserved by the rich and precious collections of puppets and marionettes, as well as the original painted backdrops by Besutti and Zaffardi. The refectory was the place where the monks consumed their meals and where two important artists worked: Girolamo Bonsignori, who painted the Last Supper on a canvas embedded in the wall, and Antonio Allegri, known as il Correggio, who between 1513 and 1514 frescoed the painted architecture in which the Cenacle was imagined inserted. It exhibits testimonies and archaeological finds of the Benedictine monastery, convent ceramics, sculptures, and terracotta and stone materials.
