The silver collection includes a large series of holy water cups, plaques, frames and reliquary holders mainly of local production, dating to the 18th century, many of which bear the Torretta trademark. These are small objects for private devotion, made of finely embossed and chiseled silver, often embellished with filigree work. Among the metal works, a notable collection of engraved and embossed copper pitchers of the 17th-18th century should be mentioned.
