The Diocesan Museum of the Cathedral of Salerno is located in the archbishop's palace. The Palace is of medieval origin and until 1700 was an important landmark of the city of Salerno. The Museum was born in 1935 and initially the works were exhibited in two small rooms. The Diocesan Museum of San Matteo, the library and the diocesan archive were placed inside the Palace in 1980. The museum collection has been collected since the 1930s by Monsignor Arturo Capone. An initial nucleus was donated by the Marquis Ruggi d'Aragona to the archbishop. The collection consists of paintings and sculptures from the Middle Ages to the eighteenth century. The works of Simone Martini, Andrea Sabatini and artists of the Neapolitan circle of the seventeenth century are part of the collection. Of great value is the ivory cycle, which is considered the most complete medieval collection in the world. Exhibited in the rooms of the museum and of great importance is the Salerno Exsultet. L'Exsultet is a liturgical chant that is sung on Easter night to ward off darkness. The document is displayed in separate cases with the original frames. The wooden crucifix from the Middle Ages preserved in the diocesan museum is a work that draws many faithful to itself. It seems that Christ bowed his head before the crucifix in repentance for the pain of death.
