Last spring, the world’s most-visited art museum, the Louvre in Paris, proposed moving its most popular artwork—Leonardo da Vinci’s Mona Lisa—to its own subterranean room. Now, that idea is becoming reality.

Amid news of the “Mona Lisa” potentially being relocated, Francesca Caruso, cultural assessor for Italy’s Lombardy region, suggested the painting be returned to Milan, where it could be displayed alongside Da Vinci’s “The Last Supper,” NBC News reported.

President Emmanuel Macron announced plans to alleviate crowds at the Paris museum and to charge higher fees for visitors from outside the European Union.
