The Diocesan Museum of Benevento is located in the area surrounding the Cathedral. The Museum was named in honor of Benedetto Bonazzi and is divided into two sections that can be visited: the pseudocrypt and the underground archaeological itinerary. The pseudocrypt presents numerous archaeological and architectural testimonies that refer to different eras and is the result of interventions begun in the Roman - Republican era. Inside the pseudocripta there is the pictorial cycle dedicated to San Barbato, dating back to the end of the 9th and the beginning of the 10th century. The museum displays artifacts of absolute historical, artistic and liturgical value: the chair of San Barbato from the seventh century; the winged figure dated to the fourteenth century; the glass ampoules and the paleochristian tombstones. In 2012 the archaeological section of the Diocesan Museum was also inaugurated. It is a museum itinerary created in the archaeological area present on the underground floor of the Cathedral. The discovery of the archaeological remains took place in 2005 and, thanks to the promoting activity of the Municipality and the Diocese, it was possible to create a museum itinerary.
