A Louvre expansion that would put La Gioconda in her very own gallery has us envisioning the most mysterious sitter in iconic rooms of art history.

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.

The Mona Lisa will get its own dedicated gallery inside the Louvre Museum which is due to undergo major renovations and expansion.
