As of 2014, the Mona Lisa hangs in the Louvre in Paris, France. It has been kept there since just after the French Revolution, though it has been moved periodically.
The Mona Lisa was painted by Leonardo da Vinci. Historians estimate that da Vinci began work on the famous painting between 1503 and 1506. The completion date is not clearly known, but it is believed that refinements were made until about 1517. Initially, the painting was inherited by a pupil of da Vinci's after his death, but it was purchased by the king and moved to the Palace of Fontainebleau. It was moved by Louis XIV to the Palace of Versailles, to the Louvre after the French Revolution and hung for a brief time in the bedroom of Napoleon before it was returned to the Louvre. In 1911, the Mona Lisa was stolen. It was believed to have disappeared for good until the thief was caught in 1913. It has since toured several places, but always returns to its home in France.
