A Swiss art gallery is returning to Italy 251 ancient artifacts worth €2 million ($2.7 million), most of them illegally excavated, Bloomberg reports.

The gallery repatriated the vases and other artifacts after similar returns by museums and collectors, according to Italian paramilitary police. The police, who did not name the gallery, said the objects were returned by the brothers who run the operation in Geneva.

The returned objects were illegally excavated in Etruscan tombs in central Italy, as well as burial sites in the southern part of the country, according to an Italian Culture Ministry news release. In the United States, the J. Paul Getty Museum and the Metropolitan Museum of Art have also returned objects of disputed origin to Italy in recent years.
