The civic museums contain over 3,400 ceramics. The collection began in 1857, with the acquisition of Renaissance majolica by the knight Domenico Mazza. The Ugolini collection, donated to the museums in 1974, is representative of the eighteenth-century "alla rosa di Pesaro" and "al ticchio" and nineteenth-century local production; the legacy also includes examples from the eighteenth and nineteenth centuries from some of the main Italian ceramic factories. The core of majolica from the Mengaroni factory, acquired by the museums in 1937, documents the artistic activity of the early twentieth century. Finally, a substantial collection of oriental and European porcelain, dating from the seventeenth to the nineteenth century, and eighteenth-nineteenth-century majolica came to the museum thanks to the testamentary donation of the Marchesa Vittoria Toschi Mosca in 1885.

The famous Medusa by Mengaroni, which caused the death of its creator, dominates the entrance to the museums. This artist is discussed in stage 18.

The civic museums are worth a specific visit.
