Italy is celebrating the return of around 600 antiquities from the U.S. They were looted years ago, sold to U.S. museums and collectors and recovered as a result of criminal investigations.

It looked more like a museum exhibition of Italian art than a crime scene, but in the Central Institute for Restoration’s offices, located inside a former women’s prison in central Rome, some 600 works of art were put on display Tuesday morning.

Italy celebrated the return of about 600 antiquities from the United States, including ancient bronze statues, gold coins, mosaics and manuscripts valued at €60 million ($106m) that were looted years ago,
