Two sets of altar cards are kept in the diocesan museum, both of them are made up of three pieces. The most important were made by the Neapolitan silversmith Aniello Treglia, active during the second half of the XVIII century.  They present floral decorative elements and figures of saint on the upper part.
The altar cards contain contain some part of the Mass, as reminders for the priests.  The central altra card was placed in the middle of the altar the others on the sides.
