The Diocesan and Capitular Museum is located in the city center of Terni. The Museum is located inside the Palazzo del Seminario of seventeenth-century origin. The architectural project was carried out on the initiative of Cardinal Francesco Angelo Rapaccioli in 1653. Even today it is possible to admire some original architectural details, such as: the windows, niches and ancient soffits of medieval origin. The Museum houses a very large collection which includes paintings from the deposits of the diocesan parishes. Among the most important works are the altarpieces depicting "the Madonna and Saints" by Marten Stellaert, "the Annunciation" by Agostino Masucci, "the praying Madonna" by Giovanni Battista Salvi known as Sassoferrato and "the Circumcision of Jesus" by Livio Agresti. The collection includes some of the most representative Umbrian-Lazio artists, including: Giacinto Brandi, Girolamo Troppa, Liborio Coccetti, Giovanni Francesco Parla, Calisto Calisti, Francesco Cincinnato and many others. Also of great importance is the collection of contemporary art consisting of works by Italian and international artists who have worked in the past in diocesan churches. The Museum preserves the paintings of the loggia made in the eighteenth century which depict sacrificial scenes and the events of the prophet Jonah.
