Both the ground floor and first floor house a series of sacred vestments.
On display on the ground floor, near the Treasure Room, are a cape, two chasubles and two dalmatics embroidered with silver thread, items used for the Pontifical mass.
Above, on the other hand, are mostly chasubles dating from the 17th – 20th centuries, handmade from fine materials, such as silk or satin.
The textiles have a variety of decorations: in fact, there are plant motifs that have either a symbolic value, such as lilies, ears of wheat and grapes, or are merely ornamental. Each form refers to a specific celebration or festivity, or to the celebrant, religious order and church in which the rite is performed.
