The museum, opened in 1988, is located in the basement of the Tempio dell'Incoronata and displays decorations and sacred vestments (furnishings for the altar and religious celebrations), candelabras, two miniated codices, and hand worked copper vases.

Of note is the precious late-Sixteenth century “Pace”, the work of Milanese enamellers, and a cross from the 1500s.

Entrance is through the Tempio dell’Incoronata.
