The Monza ampullae form the largest collection of a specific type of Early Medieval pilgrimage ampullae or small flasks designed to hold holy oil from pilgrimage sites in the Holy Land related to the life of Jesus. They were made in Palestine, probably in the fifth to early seventh centuries, and have been in the Treasury of Monza Cathedral north of Milan in Italy since they were donated by Theodelinda, queen of the Lombards, (c. 570–628). Since the great majority of surviving examples of such flasks are those in the Monza group, the term may be used to cover this type of object in general.
