The present Diocesan Museum of Sacred Art (MUDAS) in Catanzaro-Squillace, now the only museum of its kind, was born from the institutional merger of the two separate locations in Squillace and Catanzaro, established at different times, in 1984 and 1997 respectively. The two locations, situated in the historic bishops' palaces, while highlighting the original and distinct history of two once neighboring and different dioceses, now tell the new phase, which began in 1986, in which the two entities were united under the guidance of a single shepherd.
Among the exhibited items, noteworthy pieces for the Catanzaro location include liturgical vestments of Catanzaro manufacture and others, dating back to the seventeenth century, the canopy by silversmith Antonio Abate dated 1856, the silver monstrance from 1782, and the painting depicting Saint Nicholas in a study phase acquired with expertise as a mature work by Mattia Preti. For Squillace, there are sculptures from the fourteenth and fifteenth centuries from the cathedral, as well as paintings and silverware such as the so-called golden chalice from 1762 and the Borgia chasuble of Sicilian manufacture from the seventeenth century. In addition to other pieces from churches and convents no longer in existence.
