Where is the painting The Mona Lisa normally kept?

Leonardo painted it in Florence, took it to Milan then to the Amboise Palace where he lived for a couple of years. The king bought it and took it to Paris, where it entered the collections of the Louvre. Stolen and kept in Florence for a couple of years.

It is now firmly in the Louvre. It has been temporarily lent to one exhibition in New York and one in Tokyo.
