In Europe there is a museum for just about everything. The latest addition to the Continent’s vast cultural space comes with a unique twist: Italy’s new Museum of Rescued Art showcases ancient artifacts and works of art that were looted from the country but successfully recovered.

The Museum of Rescued Art was inaugurated Wednesday in a cavernous structure that is part of Rome’s ancient Baths of Diocletian. The Octagonal Hall exhibition space was designed to highlight Italy’s efforts, through patient diplomacy and court challenges, to repatriate valuable antiquities, often after decades in foreign museums or private collections.

Exhibits in the new museum will change every few months as the objects on display return to what experts consider their territory of origin, many of them places that were part of ancient Etruscan or Magna Grecia civilizations in central or southern Italy.

The inaugural exhibit revolves around some 100 of 260 artifacts recovered by the nation’s paramilitary Carabinieri art squad from America and brought back to Italy in December 2021.

The pieces on display, which were found during clandestine digs and illegally exported, include exquisitely carved Etruscan figurines and imposing painted jars from several centuries B.C. The items previously were held by museums, auction houses, and private collections.

The new Rome museum is exhibiting objects “never before seen in Italy,” the director general of Italy’s state museums, Massimo Osanna, said. In a previous role, Mr. Osanna had long been in charge of reviving the fortunes of Pompeii, the ancient Roman city near Naples that is one of the world’s most famed archaeological sites — and that itself was heavily looted by antiquities thieves of past generations.

The recently recovered antiquities are from before the Roman era, dating back to between the 8th and the 4th centuries B.C. Many of them came from the area near modern-day Cerveteri, which is awash with remnants of the flourishing Etruscan civilization in west-central Italy.

One particularly striking piece, from the 7th century B.C., is a ceramic jar, painted red on white and towering more than 40 inches high. Decorated with images of horses and cats, it depicts the mythological scene of the blinding of Polyphemus, a man-eating one-eyed creature.

The choice of the jar’s decoration probably indicates that the Etruscan elite were bilingual and “fascinated with Greek myth,” Mr. Osanna told the Associated Press in an interview. They were “Etruscan heroes that identified with Greek heroes,” he said.

The Italian culture minister, Dario Franceschini, explained the decision to opt for a series of rotating exhibits in the new museum instead of establishing a permanent collection of rescued art.

“We thought it’s right to have the pieces return to the places where they were stolen from,” Mr. Franceschini said.

In some cases, experts don’t know the exact original location of the antiquities, underlining the irreparable damage done when archaeological treasures are clandestinely snatched away. Pieces with unknown origins will be returned to the general geographic area.

The exhibition space is part of the National Roman Museum. Its current exhibit runs until October 15, then the museum will display a different batch of recovered antiquities.

While Italy proudly boasts of regaining some three million artifacts and artworks since a special Safeguarding of Cultural Heritage unit of the Carabinieri was established in 1969, it is also trying to inspire countries to give back ancient pieces that are identified with other cultures.

Earlier this month, Italy returned to Athens a frieze fragment of the Parthenon that had been in an archaeological museum in Sicily. Mr. Franceschini, Italy’s culture minister, contended that the so-called Fagan fragment was in Italy legitimately but said his country wanted to “affirm the principle of the restitution of cultural wealth to reconnect artistic historical patrimony with the places and peoples of origin.”

Some treasures have so far eluded Italy’s efforts to obtain them.

The Carabinieri commanding general, Teo Luzi, spoke wistfully at the new museum’s debut of hopes that Italy would one day reclaim “Victorious Youth,” a footless bronze statue that was found by an Italian fishing boat’s crew in the Adriatic Sea in 1964. It was eventually purchased by the J. Paul Getty Museum in California.

In 2018, Italy’s highest court ruled that the museum had to surrender the statue to Italy. The museum, insisting that the statue was fished out of international waters, has challenged the order.
