The world's most visited museum is also overcrowded, antiquated and desperate for renovations that will start next year and include separate space and tickets for Mona Lisa.

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.

Now that Leonardo da Vinci's masterpiece is moving to another room at The Louvre, other Renaissance masterpieces hanging in the same space by Titian, Tintoretto and Veronese may finally get their due.
