With upgrades including a separate room for the Mona Lisa, the renovation of Paris' Louvre Museum is expected to cost between $730 million and $825 million over the next decade.

France will launch a six-year renovation of the Louvre in Paris, enlarging the world's most-visited museum to make room for the huge crowds who now cram inside the palace on the banks of the Seine, President Emmanuel Macron said on Tuesday.

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.
