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.

French President Emmanuel Macron announced Tuesday that the Mona Lisa will get its own dedicated room inside the Louvre museum, which he said will be renovated and expanded in a major overhaul that will take years to complete.
