Archaeological Materials, Ancient Art, and Cultural Property
The Met is committed to the responsible collecting of ancient art, archaeological materials, and other cultural property, including works of art from once-colonized areas, and goes to great lengths to ensure that all objects entering the collection meet its strict collecting policies.
The Met's Provenance Initatives
In response to the systematic, widespread looting by the Nazi regime, the provenance of works that changed hands in German-occupied Europe during the Nazi era has long been an area of particular focus for The Met.
Sometimes The Met learns through its own research or from an outside source that a work should be returned to its country of origin, based on our policies and the laws of the country in which it originated. Learn about objects that The Met has returned.
